As streamlines are the utmost visualization tools of fluid flow and not the isobars, heatlines and masslines are the sufficient visualization tools of heat and mass transfers and not the isotherms and isoconcentrations respectively. Motivated by various applications of conjugate heat and mass transfer in drying, cooling, sterilization process etc., the present work aims to find out the detailed analysis of conjugate heat and mass transfer using heatlines and masslines in a trapezoidal enclosure with different heating and various massive walls in the presence of magnetic field. The main impact of the paper is the analysis of heatlines and masslines with different aspect ratios of the cavity, which has not been considered by any earlier researcher. The second order accurate finite difference approximation streamfunction—velocity formulation of full Navier Stokes equations has been used to find out the numerical solutions. The discretised non-homogeneous system of linear equations are solved by Biconjugate Gradient Stabilized method.
