Background: Heat exchangers (HE) are an integral part of power plants. Transport versions of HE impose requirements on the quality of their transient modes.
AimS: Development of a mathematical model of a compact HE as part of the environmental control system (ECS) of an aircraft.
Materials and methods: A mathematical model of an HE was developed using the finite volume method. A system of equations was obtained in the form of an implicit differential formulation. The solution was conducted using standard methods built into mathematical packages. This approach was optimal from an engineering point of view and allowed the integration of a model of an HE into the general mathematical model of an aircraft ECS.
Results. A mathematical model of aircraft secondary HE was developed, ready for integration into a full ECS model. The model was verified through static calculation using two methods accepted in the aviation industry.
Conclusions. The presented mathematical model of a compact aircraft HE was balanced in terms of the accuracy of the solution, the complexity of development, and the computing resource demands.
