摘要
Steady mixed convection flow in a square wavy cavity containing heated corrugated rods is investigated numerically. In the current work, the vertical walls are suited at a fixed temperature, and the upper and lower walls are adiabatically treated. Thermal conductivity has been calculated by Galerkin finite element methods in which computational region is discretized into small triangular portions. We have studied effects on temperature and streamlines for different Rayleigh numbers, Hartmann numbers, and numbers of undulations and fixed dimensionless amplitude A = 0.05 of right wavy wall and amplitude of corrugated rod C = 0.02. The flow is entirely steady for the range of Ra. from 103to 105 and Ha. from 0 to 50. Mixed convection of top-motivated streams covers the tenders, for example, cooling of electronic gadgets, elite execution building protections, multi-safeguard structures utilized for atomic reactors, food handling, float glass creation, heater. Various ex-aminations on cover-driven cavity stream and intensity move including different mixes of cavity arrangements, different liquids, and forced temperature slopes have been distributed in the writing much of the time.
