Stretched flows past over a deformable surfaces has numerous applications. Utilization of Hall and Ion slip effects has been considered to model three-dimensional flow of Williamson nanofluid model. The phenomena if thermal and solutal transport have ben modeled by considering Buongiorno model, modified heat and man flux theory by considering Joule heating in certain coordinate system. The derived phenomena result in the form of coupled partial differential equation (PDEs) which is simplified by using principal of boundary layer theory. The derived PDEs are nonlinear and complex in nature and are converted into ordinary differential equation (ODEs) by engaging an appropriate transformation. Afterwards, convert ODEs are handled for the solution via optimal homotopy procedure.The authenticity of applied scheme is shown by listing the comparative study against different emerging parameters. Results are displayed through graphs and tables and which confirm the authenticity of used algorithm. From the performed analysis, it is recorded that hall and slip parameters escalated the velocity field and provided deceleration in temperature and concentration fields.
