Viscous dissipation effects on mixed convection about a rotating sphere
The effect of viscous dissipation on mixed convection flow about a rotating sphere is investigated analytically. A method based on Merk's type of series expansions is used to obtain the heat transfer rate and the skin-friction coefficients. Numerical computations were carried out for Eckert num...

| description | The effect of viscous dissipation on mixed convection flow about a rotating sphere is investigated analytically. A method based on Merk's type of series expansions is used to obtain the heat transfer rate and the skin-friction coefficients. Numerical computations were carried out for Eckert number Ec ranging from 0 to 0.1, rotation parameter
B = 0, 1, 4 and buoyancy parameter ranging from 0 to 1 at various angular positions. As viscous dissipation increases heat transfer rate decreases. It is found that for
Ec > 0, a critical value of
B (say
B
cri) exist such that
Nu Re
R
−
1
2
increases as
B increases up to
B =
B
cri and then decreases.
B
cri decreases with Ec when the angle is fixed or decreases with angle when Ec is fixed. When
Ec > 0, possibly there exist a λ, say λ
cri, such that
Nu Re
R
−
1
2
increases with λ up to
λ =
λ
cri
and then decreases. Also the effect of viscous dissipation on skin friction is investigated. |
