The transfer of heat by fluid is convection.
The velocity of the fluid affects convection heat transfer by increasing the heat transfer rate. Higher fluid velocity results in better mixing of the fluid, reducing boundary layer thickness and increasing heat transfer coefficient, which enhances the convection heat transfer process.
Convection is "the transfer of heat through the motion of molecules in a fluid."
Convective heat transfer occurs in fluids, such as air or water, when the fluid moves and carries heat with it. It is represented by the point on a heat transfer curve where heat is transferred due to the movement of the fluid, creating a convective heat transfer process.
Heat transfer within a fluid occurs through conduction, convection, and radiation. Conduction is the transfer of heat through direct contact between molecules, convection is the movement of heat through the bulk movement of fluid particles, and radiation is the transfer of heat through electromagnetic waves. These mechanisms work together in the fluid to distribute heat energy and ensure thermal equilibrium.
Heat transfer can affect the fluid density at the nozzle exit, which in turn can impact the fluid velocity. An increase in heat transfer can lower the fluid density, resulting in an increase in velocity at the nozzle exit due to conservation of mass. Conversely, a decrease in heat transfer can raise the fluid density, leading to a decrease in velocity.

Convection is "the transfer of heat through the motion of molecules in a fluid."
Heat can transfer through a fluid by conduction and/or convection (with convection being the most efficient). If the fluid is a gas then heat can also transfer through it by radiation (but this does not work in liquid fluids).

Heat Transfer Fluid
Convection currents are the moving currents of fluid that transfer heat. Heat is transferred through the fluid as warmer, less dense fluid rises and cooler, denser fluid sinks, creating a continuous circulation pattern that transfers heat throughout the fluid.
