Abstract The present study analyzes conjugate heat transfer in a differentially heated square cavity. left wall of the cavity is cooled, and right while horizontal walls are adiabatic. Normalized continuity, momentum energy transport equations were solved with aid COMSOL Multiphysics 5.4 software. effects Rayleigh number range 10 2 ?
