inside a cone due to a point sink at the vertex of the cone have been investigated. The fluid viscosity and thermal
conductivity have been assumed to be temperature dependent. The governing fluid flow equations with boundary
conditions have been transformed into set of coupled ordinary differential equations with the help of similarity
transformations and solved Runge-Kutta method with shooting technique. The effects of Schmidt number, variable
thermal conductivity parameter, mixed convection parameter, buoyancy parameter and chemical reaction parameter
on velocity distribution, temperature distribution, concentration distribution, heat transfer rate and coefficient of skinfriction
have been investigated. It is observed that concentration decreases with increasing Schmidt number and
temperature increases with increasing values of thermal conductivity parameter. Also with increasing values of mixed
convection parameter, velocity, temperature and concentration decreases. The present study is relevant in conical
nozzle and diffuser flow problems exist in petroleum and chemical industries.Forced convection, Point sink, Variable viscosity, Heat transfer, Skin friction5963http://jafmonline.net/JournalArchive/download?file_ID=15317&issue_ID=206V.Bishtvandanabisht7@gmail.com`NoDepartment of Mathematics, SRMS, CET, Bareilly -243202, UP, INDIA`
