Numerical investigation of Hydro-magnetic flow of air in three different geometries of open cavity
2014
MHD or Magnetic hydro dynamics of an open cavity with three different depths is investigated numerically in this paper. The SIMPLE algorithm is utilized in order to solve the equations of conservation of momentum and energy. Isothermal lines and streamlines of the flow are presented for 3 Ha numbers: Ha=10, 20, and 30 for each of the three cavity depths: L, 2L, and 3L. Then the Nu number of the heated wall has been studied and compared for each Ha number and cavity depth. It was observed that in the case of depth L and Ha=30 the maximum heat transfer is achieved while the minimum heat transfer rate is for the case of depth 2L and Ha=20.
