Natural convection flow over the wavy cone with temperature dependent viscosity in case of surface heat flux

Abstract

The ,,(feet of temperature dependent viscosity ,,(1), on slcady two dimensional natural convect;oll flow along a vertical wavy cone with uniform surface heat flux has been investigated in this dissertation, Three different rlln~ti()n" for temperature dependent viscosity have been considered with very large Grashof number (Gr). Using the appropriate variable, the basic equations are transformed 10 nondimensional boundary layer equations and then solved numerically employing implicit finite difference method. A highly efficient method, namely. StraightfOlward Finite Difference (SFFD) method has been used to solve the non-dimensional boundary layer equatioll. The program code of this method has been developed in FORTRAN 90. Tne effects of the pertinent parameters, sueh as viscosity variation parameter, amplitude of waviness and angle of the cone, on the velocity profile, temperature profile, velocity vector field. skin friction, average rate of heat transfer. streamlines and isotherm have been di'>Cu~~ed.The results have been shown graphically by lIlilizing the visualizing ~ofh'are 'l'echplot. The results obtained from the numerical study have been discussed emphasizing the physical prospects.
