Effects of Chemical Reaction and Pressure Work on Free Convection over a Stretching Cone Embedded in a Porous Medium

در اين مقاله يك مقدمه از حل معادلات ديفرانسيل جزيي با تبديل به دستگاهي از معادلات ديفرانسيل معمولي و حل آنها با استفاده از روش هاي عددي رونگه و كوتاي مرتبه چهارم ارايه مي گردد.

Laminar free convection from a stretching cone embedded in the porous media with effects of pressure work, heat generation, thermal stratification and chemical reaction are considered. The governing partial differential equations have been transformed by a similarity transformation into a system of ordinary differential equations, which are solved numerically using a fourth order Runge-Kutta scheme with the shooting method. Solutions obtained in terms of local heat and mass transfer, velocity, temperature and concentration profiles for the values of physical parameters are displayed in both graphical and tabular forms.
