Concentration and Thermal Analysis of immiscible Tangent hyperbolic fluid with distinct viscosity through horizontal asymmetric channel: Theoretical and Observational study

This study examines cilia induced Tangent hyperbolic fluid flow with distinct viscosity, density in addition to thermal conductivity through horizontal asymmetric channel in two adjacent layers. The impact of mass and heat transfer in two adjacent layers with continuity at the interface is considered. The governing equations for double-layer fluid flow was modelled and simplified via well-known approximation long wavelength and small Reynolds number. The subsequent equations with boundary conditions provide exact solution for the velocity profile, temperature field and concentration distribution in both layers. The outcomes of occurring parameters on temperature, velocity and concentration field are explained graphically. The major findings show that velocity field and temperature field are extreme in internal fluid layer and concentration distribution is highest at external fluid layers. In both the layers by rising viscosities, thermal conductivities, fluid parameters and temperature profile increases. Potential applications for the current work include mucus clearance from respiratory tract, microfluidics, oesophageal transport, bio fluid mechanism and other fields of physiology.
