Convection is an important fluid mechanics concept because it describes how heat and other properties are transferred within fluids. The convection term is used to describe the transfer of heat or other properties within a fluid due to the movement of the fluid itself. Convection can be either forced or natural. Forced convection occurs when a fluid is forced to move by an external source, such as a pump or fan. Natural convection occurs when a fluid is heated and the resulting density gradient causes the fluid to circulate.

Q: What is a convection term?

A: A convection term is a mathematical term used to describe the movement of fluids or heat.

Q: What is the convection term in the Navier Stokes equation?

A: The convection term in the Navier Stokes equation is a measure of the rate of change of momentum of a fluid due to the fluid’s motion.

Q: Why convection occurs in fluid?

A: Convection occurs in fluids when the fluid is heated and expands. The expanding fluid rises and the colder, denser fluid sinks. This movement creates a convection current.
