Heat Transfer Inside a Zigzag Channel CFD Simulation, ANSYS Fluent Training

The present study simulates the heat transfer of water flow through a zigzag channel by ANSYS Fluent software. The number of times the channel goes up and down horizontally is equal to ten, and the angle of the channel in each of these ten steps is assumed to be 15 degrees for the first model and 45 degrees for the second model. Since the flow Reynolds number has a low value of 107, the flow is defined as laminar. Water flows into the channel at a velocity of and a temperature of K and exits the end of the channel at a pressure equal to the atmospheric pressure. The lower wall of the zigzag channel is insulated and the upper wall has a constant temperature of K.
