Change in internal energy of viscoelastic fluid flow between two rotating parallel plates having variable fluid properties

Abstract

In this study, second-grade fluid is taken into account in order to examine its rotating behavior with heat and mass transfer effects. The analysis is carried out between two parallel plates. The study of heat and mass transfer is accomplished by taking the effects of non-constant diffusivity, conductivity and viscosity. A chemical reaction is taken in the form of activation energy. Moreover, it is assume that the kinetic energy of the fluid particles is converted into internal energy. Signifying fundamental equations are tracked by constructing numerical form solutions for velocity, temperature and concentration distributions, while assuming variable fluid properties and internal energy change. Bvp4c technique is employed by considering second-grade fluid parameter and variable fluid properties to be very small. The impact of emerging parameters on velocity, temperature and concentration distributions is examined through graphical depiction. A direct relation is taken between concentration and diffusivity, temperature and thermal conductivity, whereas the indirect relation is assumed for viscosity. Heat transfer is minor for a fluid with variable conductivity and viscosity as likened to the fluid with constant conductivity and viscosity. For uplifting values of rotation parameter, the fluid velocity magnifies.
