Description
Introduction
A heat exchanger is a system used to transfer heat between two or more fluids. Heat exchangers are used in both cooling and heating processes. The fluids may be separated by a solid wall to prevent mixing, or they may be in direct contact. They are widely used in space heating, refrigeration, air conditioning, power stations, chemical plants, petrochemical plants, petroleum refineries, natural-gas processing, and sewage treatment. The classic example of a heat exchanger is found in an internal combustion engine in which a circulating fluid known as engine coolant flows through radiator coils, and air flows past the coils, which cools the coolant and heats the incoming air. Another example is the heat sink, which is a passive heat exchanger that transfers the heat generated by an electronic or mechanical device to a fluid medium, often air or a liquid coolant.
Helical Heat Exchanger Project description
In this project, the heat transfer inside a helical heat exchanger is investigated by ANSYS Fluent software. The helical heat exchanger consists of a number of coils (helical tubes) with a helix curve (similar to a spring) that are embedded in a shell. To increase the heat transfer level, several pipes are placed in a spiral format next to each other, and all are connected to one inlet and outlet. Numerous experimental studies have been performed on helical tubes’ flow and heat transfer characteristics. The energy equation is activated to obtain temperature distribution inside the computational domain. The standard k-epsilon model is exploited to solve turbulent flow equations. It should be noted that the ideal gas model has been used to determine the density changes in proportion to temperature.

Prof. Stewart Kautzer –
What model adjustments are required if I want to simulate a transient response in the helical heat exchanger instead of a steady state?
MR CFD Support –
To simulate a transient response, you’ll need to switch from the steady solver to the transient solver in ANSYS Fluent. Additionally, you’d have to adjust your initial conditions and set appropriate time step sizes and total simulation time to capture the dynamic behavior of the heat exchange process. It’s important to ensure that your mesh can resolve the flow features over time, and you may need to activate transient models for turbulence if the flow features change rapidly.
