Recently there is a need to enhance the cooling capabilities required in many industrial applications. Therefore it is important to know the factors for system’s disorderliness. This work is based on the study of entropy analysis in fluid transport phenomenon by peristalsis. Mixed convective flow in compliant wall channel is considered. Here third grade fluid is considered. Effect of gravity is also encountered. Magnetohydrodynamic and Joule heating are part of flow modeling. Energy equation is addressed subject to viscous dissipation and variable thermal conductivity. Resulting system is solved with the help of NDSolve command in Mathematica. Proper attention is given to the study of velocity, temperature and entropy analysis. This analysis is carried out via graphical results for different embedded parameters. Graphs for heat transfer coefficient are also plotted and analyzed.
