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 reduces. In addition, rheological characters have major impact temperature distribution due to these, falls lower than free stream within region.
