Unit Converters
- Unit Conversion Calculator
![[GOOD]](Icons/smiley.gif)
- A fairly complete unit converter in javascript that is easy to use.
Calculators
- RPN
Calculator (click to open a small new window)
- A scientific RPN calculator written in JavaScript. Has a clean interface
and many functions. Use it whenever you haven't got your HP around.
- Scientific
Calculator (click to open a small new window)
- A scientific calculator written in JavaScript. Works well for those of
you who don't like reverse polish notation.
y+ Estimation
- Viscous Grid Spacing
Calculator
- A JavaScript that helps you to estimate at what normal distance from a
wall you should place your first grid-line. This is one of those wonderful
little tools that saves you from learning a formula!
- Viscous Grid
Spacing Calculator
- Another y+ estimation script by CHAM. Uses a slightly different approximation
formula but also works great.
Compressible Flow
- Compressible Aerodynamics Calculator
- A JavaScript to compute standard relations for compressible flow of a perfect
gas. Three sets of relations are included; isentropic flow, normal shocks
and oblique shocks. Written by William Devenport.
- CFD Calculators
- A few simple calculators from adapco-online - compressible flow state calculation,
ideal gas law, properties of air and a unit converter.
Simple Cases, Pipes, Channels etc.
- Pipes, channels, hydrology, groundwater, tank volume and more
- Many small java-applets from LMNO Engineering. You have to pay a fee to
get access to all but there are many free calculators also. Nice.
Heat Transfer
- The Thermal Wizard
- A very nice collection of online calculators provided by Maya Heat Transfer
Technologies. The main focus is on heat transfer applications - conduction,
convection and radiation in simple geometries. You can also find material
data, a unit converter and a few simple head-loss computations.
Cycles and Processes
- Power Cycle Analysis Online Calculator
- Computes efficiencies etc. for various thermodynamic cycles - Carnot cycle,
Brayton cycle, Otto Cycle, Diesel Cycle, Magentohydrodanmics ... Provided
by Engineering Software as a part of their Free Online Calculators section.
- Power Cycle Components/Processes Online Calculator
- Simple calculators for the following basic cycle components: isentropic
compression, stoichiometric combustion (Coal/Oil and Gas) and isentropic
expansion. Provided by Engineering Software as a part of their Free Online Calculators section.
