Convection is the process of heat transfer using the movement of fluids. In forced convection, externally induced flow is used for heat transfer.
Natural convection is the process of heat transfer through a fluid in the presence of bulk fluid motion by natural methods.
Thermal conductivity is the tensor property of a medium which defines its heat conductive efficiency. It also expresses the anisotropy of the medium

The fluid enters through the same end in a parallel flow heat exchanger and travels adjacent to each other in a parallel manner in the same direction, while in the counter flow heat exchanger
Fins are the extended surfaces that are used to raise the heat transfer rate by means of an increase in convection to or from the environment.
Critical heat flux can be defined as the point in the boiling curve where the nucleate film boiling converts into film boiling causing the continuous separation of vapour film through the heater and the liquid.
Stefan Boltzman’s law determines the total energy radiated by an object by using the value of its absolute temperature. This law states that objects radiate energy based on the fourth power of their absolute temperature
