Abstract
This work explores the effect of activation energy on bioconvection flow of oxytactic microorganisms with nano-encapsulated phase change materials in complex shaped enclosure. The inner wavy wall is partially fixed at the constant high temperature. The proposed problem has been modeled first using the conservation laws and then simulated by utilizing finite element method. The discretized system of nonlinear algebraic equation is computed using the Newtons method. The obtained results have been analyzed for the several important controlling parameters. It has been observed that the vortex centers have been established near the adiabatic walls for lower values of Lewis number. The average Sherwood number and density of motile microorganism are the increasing functions of chemical reaction parameter. Moreover, the average Nusselt number declines with rising values of Peclet number.
