Abstract
The pressure loss in a cooling channel was investigated by conducting a numerical analysis, which was performed with a different channel angle in the axial direction, velocity of flow, and diameter of channels. The pressure loss did not change much with respect to the different channel angle. However, the pressure loss tended to decrease if the diameter of the channel increased and the velocity of the flow decreased. The results were quantified by a nondimensional method and compared to an existing experimental equation to validate them. The data obtained by this study would be helpful in the design process of a cooling channel considering the pressure loss.
