Abstract

Abstract: Mechanism of pharmaceutical procedures, nuclear reactor cooling, pace technology, thermal insulation, crushing, geothermal reservoirs and enhanced oil recovery involving chemically reactive systems has a significance in mass transport. Additionally, nanofluids with swimming microorganisms have great significance in medicine, cancer therapy, micro fluidics devices and enzyme biosensor. Main focus of present communication is to analyze the impact of melting phenomena and nonlinear chemical reactions aspects on transient bioconvection flow of sutterby nanoliquid with gyrotactic microorganisms and heat source/sink. Additionally, activation energy and nonlinear radiations influences are invoked. Furthermore, a novel revised nanofluid model disclosed by Kuznetsov and Nield is applied to measure heat and mass transport. The basic PDEs embodying the conservation of microorganisms, nanoparticle concentration, energy, momentum and mass are persuaded into highly nonlinear coupled ODEs. Numerical solutions are executed via Runge-Kutta Fehlberg (RK45) scheme for the presence and absence of melting process. Comparative analysis with existing study are performed and reflected in excellent agreement. It is interesting to notice that microorganism field and nanoparticle concentration are depressed due to augmentation of reaction rate parameter for M = 0.0 and M = 0.5 . It is also pointed out that heat transfer rate is better for the case M = 0.5 when compared to the case.
