List-I List-II
A. Forced convection 1. Reynolds, Grashof and Prandtl number
B. Natural convection 2. Reynolds and Prandtl number
C. Combined free and forced convection 3. Fourier modulus and Biot number
D. Unsteady conduction with convection at surface 4. Prandtl number and Grashof number

The correct matching of the type of heat transfer with the governing dimensionless parameter is as follows:

A. Forced convection: Reynolds, Grashof and Prandtl number
B. Natural convection: Fourier modulus and Biot number
C. Combined free and forced convection: Reynolds and Prandtl number
D. Unsteady conduction with convection at surface: Prandtl number and Grashof number

Explanation:

Forced convection:
For forced convection, where the flow of fluid is induced by an external source, the governing dimensionless parameters are the Reynolds number, Grashof number, and Prandtl number. The Reynolds number characterizes the ratio of inertial forces to viscous forces and determines whether the flow is laminar or turbulent. The Grashof number represents the ratio of buoyancy forces to viscous forces and determines the dominance of natural or forced convection. The Prandtl number represents the ratio of momentum diffusivity to thermal diffusivity and determines the thermal boundary layer thickness.

Natural convection:
For natural convection, where the flow is driven solely by buoyancy forces, the governing dimensionless parameters are the Fourier modulus and Biot number. The Fourier modulus represents the ratio of conductive heat transfer to convective heat transfer and determines the dominance of conduction or convection. The Biot number represents the ratio of convective heat transfer resistance to conductive heat transfer resistance and determines the relative importance of convection compared to conduction.

Combined free and forced convection:
For combined free and forced convection, both the Reynolds number and Prandtl number play a significant role. The Reynolds number characterizes the flow regime, while the Prandtl number characterizes the thermal properties of the fluid.

Unsteady conduction with convection at the surface:
For unsteady conduction with convection at the surface, the governing dimensionless parameters are the Prandtl number and Grashof number. The Prandtl number represents the ratio of momentum diffusivity to thermal diffusivity, while the Grashof number represents the ratio of buoyancy forces to viscous forces. These parameters determine the behavior of the fluid flow and heat transfer in unsteady conduction situations.

Therefore, the correct matching of the type of heat transfer with the governing dimensionless parameter is option (c) 2 4 1 3.
