What is Convection?

Convection is the process of heat transfer by the bulk movement of molecules within fluids such as gases and liquids. The initial heat transfer between the object and the fluid takes place through conduction, but the bulk heat transfer happens due to the motion of the fluid. Convection is the process of heat transfer in fluids by the actual motion of matter. It happens in liquids and gases. It may be natural or forced. It involves a bulk transfer of portions of the fluid.

What are the Types of Convection?

There are two types of convection, and they are: Natural convection: When convection takes place due to buoyant force as there is a difference in densities caused by the difference in temperatures it is known as natural convection. Examples of natural convection are oceanic winds. Forced convection: When external sources such as fans and pumps are used for creating induced convection, it is known as forced convection. Examples of forced convection are using water heaters or geysers for instant heating of water and using a fan on a hot summer day.

How to Calculate Local Skin Friction Coefficient for Turbulent Flow on Flat Plates?

Local Skin Friction Coefficient for Turbulent Flow on Flat Plates calculator uses Local Friction Coefficient = 0.0592*(Local Reynolds Number^(-1/5)) to calculate the Local Friction Coefficient, The Local Skin Friction Coefficient for Turbulent Flow on Flat Plates formula is defined as the function of local Reynolds number. In the turbulent core of the boundary layer the eddy viscosity may be as high as 100 times the molecular value experienced in the laminar sublayer, and a similar behavior is experienced for the eddy diffusivity for heat compared to the molecular diffusivity. To account for the Prandtl number effect over the entire boundary layer a weighted average is needed, and it turns out that use of Pr^(2/3) works very well and matches with the laminar heat-transfer–fluid-friction analogy. Local Friction Coefficient is denoted by C_fx symbol.
