► Daikin Applied achieves performance improvement using TURBOdesign Suite
  19 Apr, 2018 

Daikin Applied of Minneapolis, Minn, a fortune 1000 company and the largest heating, ventilation, air conditioning (HVAC), and refrigeration company in the world developed a new, ultra-efficient compressor design potentially capable of achieving multimillion dollar performance gains by using TURBOdesign Suite. Turbomachinery design engineers and original equipment manufacturers (OEMs) worked to achieve higher performance levels to meet U.S. and international efficiency standards can take advantage of the 3D inverse design software system, TURBOdesign Suite.

In general, one point of efficiency gain equates to about $1 million (U.S.) of profit," says Guy Phuong, Development Engineer at Daikin Applied. "Daikin Applied’s target performance gain for this project using the TURBOdesign Suite software is 2.5 points of efficiency gain. We already have achieved more than a two-point compressor efficiency improvement."

The HVAC system represents a large percentage of a building’s energy use. Since the 1980s, manufacturers of HVAC equipment like Daikin Applied have worked to make their systems more efficient. This was originally driven by rising energy costs and therefore customer demand. It was mandated by governmental standards like those set by the U.S. Environmental Protection Agency Engine Testing Regulations and Europe’s Ecodesign Directive. There are several methods for making HVAC systems that meet or exceed new standards, including making individual components such as air conditioning system compressors more efficient.

"Our 3D inverse design optimization technology provides innovative solutions while reducing development time and costs," said Professor Mehrdad Zangeneh, founder and managing director of ADT. "By using the TURBOdesign Suite, Daikin Applied engineers were able to apply the 3D inverse design approach to directly use knowledge of detailed fluid dynamics, as provided by computational fluid dynamics (CFD) and detailed measurements, to arrive at a breakthrough solution that met efficiency goals."

In the 3D inverse design approach enabled by the TURBOdesign Suite, the blade geometry is computed for a given pressure or loading distribution. Since 3D pressure distribution controls the viscous behaviour of the flow, by controlling the 3D pressure field, it is possible to directly use the detailed information provided by CFD solutions to arrive at a choice of optimum loading and control particular sources of performance loss in turbomachines. Read the case study in full.

Inverse Design offers a means by which turbomachinery designers can produce breakthrough designs in short order with lower costs. Our joint webinar with ASME: Maximizing Turbomachinery Performance with Inverse Design led by industry experts on the 24th of April will enable viewers to understand:

How TURBOdesign's Inverse Method is applied to modern turbomachinery design How Inverse Design addresses some of the key challenges facing turbomachinery manufacturers today The key steps needed to maximize the performance and efficiency of a design How to optimize designs using TURBOdesign Suite and how TURBOdesign links with analytical tools such as ANSYS and Star-CCM+ How Daikin Applied has used TURBOdesign Suite to optimize their chiller compressor designs for dramatically higher efficiencies and breakthrough performance

► Investigation on Flow Characteristics of Pump-Turbine Runners With Large Blade Lean
  12 Apr, 2018 

Frequent changes in the operating modes pose significant challenges in the development of a pump-turbine with high efficiency and stability. In the current publication on Investigation on Flow Characteristics of Pump-Turbine Runners With Large Blade Lean in the Journal of Fluids Engineering, two pump-turbine runners, one with a large positive blade lean and the other with a large negative lean, are investigated numerically and experimentally. These two runners are designed by using the optimum stacking condition at the high pressure edge (HPE). The experimental and the numerical results show interesting outcomes on efficiency performances and pressure fluctuations. The internal flow field analyses clarify the effects of the blade lean on the pressure distribution around the runner blades. In the turbine mode at partial load, the negative blade lean can control flow separation in the high pressure side of the runner and then reduce the pressure fluctuations in the vaneless space.

Pumped storage power stations are experiencing rapid development in China with the increasing development of smart grid and extensive development of nuclear and wind power stations for renewable energy. As a key component of the mechanical part of pumped storage power stations, the reversible pump-turbine has the function of water pumping and electricity generation as the load varies in the electricity grid. High efficiency, no cavitation, and good stability are important standards to evaluate the performance of a pump turbine unit. Compared with the efficiency and cavitation, it is difficult to evaluate the hydraulic stability due to its unstable characteristics in the design stage.

Hydraulic stability in a pump-turbine has become more and more prominent with the increase of the pump-turbine’s capacity. In the pump-turbine, pressure fluctuations may arise from system instabilities generated by a combination of pump-turbine runner’s S-shape characteristic and a hydraulic system or due to flow instabilities, such as vortex shedding, rotating stall, draft tube vortex, and so on. These pressure fluctuations can induce mechanical vibrations and even premature mechanical failures.

It has been recognized that pressure fluctuations in the space between runner blades and guide vanes are the most detrimental to hydraulic stability. The space between the runner blades and the guide vanes is usually referred as the vaneless space. It has been shown that within the vaneless space, rotor–stator interactions (RSI) are the primary cause for the pressure fluctuations in the turbomachinery.

Many experimental and numerical studies have been made on pressure fluctuations in both model and prototype pump turbines. Near the best efficiency point (BEP) for both the turbine and pump modes, the amplitudes of pressure fluctuations are low and the dominant frequency was blade passing frequency. At off-design conditions, amplitudes of the pressure fluctuations increased and low frequency components occur due to the unsteady vortex formation in the runner and/or guide vanes. The alternate vortex formation leads to unsteady momentum exchange between runner blades and guide vanes and is accordingly associated with pressure fluctuations.

Many studies have been done on the RSI’s mechanism and characteristics in pump-turbines. However, few investigations have been made in the design stage to reduce the pressure fluctuations and their unsteadiness. Larger vaneless space and higher height of the guide vanes can bring down the pressure fluctuations in the vaneless space.

However, these parameters inevitably affect the efficiency of the pump-turbines. Leaned blades have been used extensively in turbomachinery over the last couple of decades. The main effect of the blade lean is to introduce a spanwise blade force, and then the loading distribution on the blade surface is changed. Blade lean can be used as a powerful tool to control blade loading, discharge angle, and mass flow distribution along the span. It has been noticed that the lean at the high pressure edge (HPE) on the runner can disperse the flow impact between the guide vanes and the runner blades in the pump-turbine.

In this paper, two reversible pump-turbine model runners, one with a big positive blade lean and the other with a big negative blade lean, are investigated. Both experimental measurements and numerical simulations are made for these two runners. The characteristics of efficiency and pressure fluctuations are presented and the effects of the blade lean angles on the internal flow field are discussed. The results offer guidance to reduce the pressure fluctuations in the pump-turbines while maintaining higher efficiency.
