Abstract

In this communication, A numerical solution strategy has been devised to compute entropy in a thermo-fluidic system comprising micropolar fluid in a Darcian regime bounded by a vertically moving plate experiencing time-dependent suction. The Crank- Nicolson numerical scheme exploited to solve the governing equations results in a tri-diagonal block matrix system. The resultant system is then solved by the Thomas algorithm, which provides pertinent quantities of interest. The velocity and thermal fields are used to compute entropy generation. The profiles for entropy generation and Bejan number are portrayed and discussed.
