Model and animation by Sheldon Imaoka. [ANSYS and CFX 10.0]
Zipped AVI and MPG animations of MEMS thermoelectric power generator converting heat from combustion into electrical energy. The MFX solver (ANSYS and CFX FSI solver) is used to couple the energy equation between the fluid domain and the solid (thermoelectric) domain. Combustion is modeled in CFX that provides the heat source, which is passed to ANSYS. ANSYS sends temperatures to CFX, and this process is iterated until convergence is achieved for a given timestep. The temperature gradients then cause a voltage drop across the thermoelectric device (Seebeck effect). Joule heating, orthotropic material properties, thermal contact also considered.
