Description
Description
The present problem deals with the simulation of a plate heat exchanger called CHEVRON by ANSYS Fluent software. We perform this CFD project and investigate it by CFD analysis.
In this model, water acts as both hot and cold fluid flow in a heat exchanger. The plates between the two flows and all the heat exchanger walls are aluminum, which is responsible for the heat transfer between the cold water and the hot water flow. This project investigates the heat transfer between two hot and cold fluids through a chevron plate heat exchanger.
The 3-D geometry of the present model is designed by Design Modeler software. Since the model is related to the plate heat exchanger, it consists of two main parts: the hot water flow zone and the cold water flow zone. The separator plates (chevron) determine the boundary between these two flows.
The unstructured mesh of the present model is carried out by ANSYS Meshing software. The element number is equal to 638892.
Chevron Methodology
The hot and cold velocities are equal to 0.25m/c, while the temperature equals 283.15k and 343.15k for cold and hot water, respectively. Standard K-e model applying a Steady-State solver is used for this CFD simulation
Chevron Conclusion
Chevron heat exchangers are more efficient than other plate heat exchangers because of the turbulent flow on both sides, which leads to a better heat transfer performance considering the shape of chevron plates, including grooves.
The particular configuration of the chevron plates increases the contact surface compared to standard plates, which directly leads to a higher heat transfer rate between cold and hot fluids.
After resolving the flow, the cold output temperature is computed as equal to 300.8757 k, and the hot output temperature is computed as equal to 325.714 k. Therefore, the temperature difference between the cold inlet and outlet is 17.72 degrees, and for hot water, this value is equal to -17.436 k.
Also, the total heat transfer rate on the plate is computed as equal to 1440.7727 W.
The average Nusselt number (Nu=((q’*d)/k(Tb-TW))) is computed equal to 593.432. Also, the pressure drop is about 610pa to 690pa on cold and hot sides, respectively. Finally, by using the formula below, the heat load in this project is computed as equal to 9,980.04 J/s. (Q.=M.C)

How do you generally handle a high-quality mesh of these kinds of complex geometries? I usually challenge to it
MR CFD Support –
The simulation uses ANSYS Meshing software to generate a high-quality mesh for the complex geometry of the chevron plates. The software allows us to refine the mesh in areas of interest, ensuring that we accurately capture the thermal and fluid flow phenomena.
Mrs. Lempi Murray –
What are the benefits of using a chevron plate heat exchanger over a flat plate design?
MR CFD Support –
Chevron plate heat exchangers have corrugated plates that create a swirling flow, which enhances heat transfer and reduces fouling. This can result in higher efficiency and longer operational life compared to flat plate designs.
Wilma Gibson –
I’m looking for a simulation of a double pipe heat exchanger. Can you help with that?
MR CFD Support –
Absolutely! We can certainly help with simulations of double pipe heat exchangers. Please provide more details about your requirements, and we’ll do our best to accommodate your request.
Brandy Little –
How is the effectiveness of the heat exchanger calculated in the simulation?
MR CFD Support –
The effectiveness of the heat exchanger is calculated as the ratio of the actual heat transfer to the maximum possible heat transfer. This is determined using the temperatures and flow rates of the hot and cold fluids.
