Thermo-fluid-mechanical simulations are performed to reproduce the operational conditions of a screw pump, assessing its efficiency in handling different fluids and capturing the associated heat-exchange phenomena. The problem arises from the pump’s inability to properly heat-up fluids during operation, which compromises performance and reliability.

By developing an optimized numerical model, we are able to simulate highly complex multi-physics interactions (fluid dynamics and thermal transfer) within a reasonable computational time (few hours instead of several days).
