Abstract
The theme of this paper is to scrutinize the irreversibility analysis in hydromagnetic flow of Reiner-Rivlin nanoliquid due to stretching rotating disk. Entropy expression is developed by first and second laws of thermodynamics. Joule heating, radiation and dissipation are scrutinized. Brownian and thermophoresis diffusion characteristics are addressed. Here our main aim is to discuss entropy and thermal transportation analyses. Furthermore isothermal quartic autocatalytic chemical reactions are discussed at catalytic surface. Partial differential equations (PDEs) are reduced to ordinary one (ODEs). ND-solve method is used to get convergent solutions for the obtained ordinary differential equations. Characteristics of different sundry variables on thermal field, velocity, concentration and entropy generation rate are discussed. Skin friction, moment coefficient disk pumping efficiency (entrainment velocity) and Nusselt number against various influential variables are analyzed through Tables. An opposite trend is noticed for both velocity and temperature distribution for magnetic parameter. Higher Reiner-Rivlin liquid parameter improves the radial and axial velocity components. Similar impact is observed for both temperature distribution and entropy generation against magnetic parameter and Brinkman number. An increment in concentration is noted against thermophoresis parameter. Larger estimation of radiation variable leads to augments the temperature distribution. A reduction occurs in entrainment velocity (pumping efficiency) and moment coefficient versus fluid variable. Higher stretching parameter leads to reduce the skin friction coefficient.
