The boundary layer existence in divergent porous channel of non-Newtonian Casson fluid with heat transfer presence suction/blowing and viscous dissipation is studied. Nonlinear coupled ODEs are obtained from governing PDEs the conditions under which structure for exists by controlling backflow explored. Numerical solutions also using "bvp4c", a MATLAB package. study reveals that if mass suction exceeds certain amount dependent on parameter then only flow possible as increases, requirement...

Abstract This work is concerned with a steady 2D laminar MHD mixed convective flow of an electrically conducting Newtonian fluid low electrical conductivity along heat and mass transfer on isothermal stretching semi-infinite inclined plate embedded in Darcy porous medium. Along strong uniform transverse external magnetic field, the Soret effect considered. The temperature concentration at wall are varying distance from edge plate, but it far away plate. governing equations necessary...

Abstract A symmetry analysis of steady two-dimensional boundary layer stagnation-point flow and heat transfer viscous incompressible non-Newtonian power-law fluids over a nonlinearly shrinking/stretching sheet with thermal radiation effect is presented. Lie group continuous transformations employed to the equations, that gives scaling laws self-similar equations for special type velocity ( <m:math xmlns:m="http://www.w3.org/1998/Math/MathML"> <m:mi>c</m:mi> <m:mrow> <m:msup> <m:mi>x</m:mi>...

The nanofluid and porous medium together are able to fulfill the requirement of high cooling rate in many engineering problems. So, here impact various shapes nanoparticles on unsteady stagnation-point flow Cu–H 2 O a flat surface is examined. Moreover, thermal radiation viscous dissipation effects considered. problem governing partial differential equations converted into self-similar coupled ordinary those numerically solved by shooting method. computed results can reveal vital findings...

The effect of thermal radiation on mixed convective flow a copper–water nanofluid past porous shrinking cylinder with homogeneous–heterogeneous reactions is studied.

Separation control and formation of boundary layer Newtonian flow in a diverging perme-able channel Darcy-Forchheimer porous material having suction/injection are discussed. Self-similar equations from governing acquired existence conditions for structure derived using nature velocity gradient inside layer. It reveals that if sum Darcy permeability parameter twice Forchheimer exceeds 2, then the always exists with all type mass even without suction/injection. Also, suction goes beyond 22,...

A study with existence of multiple exact solutions has its own importance, and if the is performed for a viscoelastic fluid, then attraction becomes very high. So, here an attempt performed, where flow two types fluids heat transfer due to shrinking permeable sheet described. In energy flow, impacts thermal radiation variable temperature wall are simultaneously undertaken. By using similarity approach, in addition single solution, dual triple closed-form field obtained some specific...
