Hey..I am doing a research on solar updraft tower and i want to use ANSYS CFX to simulate the solar updraft tower. I am having problems with the boundary conditions.. For the inlet i have used the boundary type OPENING with a defined value of static pressure. The outlet i have used the boundary type OUTLET with static pressure as 0Pa.For the base, the collector wall and the chimney wall i have used the boundary type WALL with mass and momentum as free slip wall and heat transfer as adiabatic.. For the domain i have used air ideal gas with buoyancy model as buoyant and i have specified the gravity and the reference density as well as the reference location. for the heat transfer model i have used total energy and the turbulence model as laminar. i also have provided the value for insolation for the collector..Can someone help me with the boundary conditions for the Solar Updraft Tower...
