Transportation of Marangoni convection and irregular heat source in entropy optimized dissipative flow

This paper is about entropy generation in Marangoni convective flow due to rotating disk with irregular heat source. Nonlinear mixed convection radiative flow is considered here. Exponential base heat source is addressed. Subsequent equations are transformed to the ODE's by using generalized Karman's variables. Results are found by using NDSolve MATHEMATICA. Through graphical illustration velocity, temperature, Bejan number and entropy generation are discussed. Axial velocity enhances via Marangoni number while temperature decays. Velocity is greater via larger nonlinear thermal convection parameter. Entropy rate boosts up for variation of nonlinear convection parameter and Marangoni number. Bejan number decays against Brinkman number and nonlinear convection parameter.
