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.
