The Impact of Non-Uniform Heat Source/Sink on Chemically Reacting MHD Flow Over An Expanding Sheet

摘要

The impact of uneven heat source/sink on the magnetohydrodynamic liquid film flow of Casson fluid in the presence of chemical reaction is investigated theoretically. The transformed governing boundary layer equations are solved numerically by adopting the bvp4c Matlab package. The impact of pertinent parameters, namely, Casson parameter, non-uniform heat source/sink parameters, chemical reaction parameter, magnetic field parameter, unsteadiness parameter and film thickness parameter on the flow, thermal and concentration fields are discussed with the help of graphs. Numerical illustrations of local Nusselt and Sherwood numbers are presented and discussed with the help of tables.
