Heat transfer simulation

The safety and efficiency of any nuclear power plant depend on the rate at which coolant systems can extract heat energy from the reactor. The thermal-hydraulic performance of a coolant system depends on highly geometry-dependent transient multi-phase flow phenomena (including boiling, cavitation, and condensation), which operate across a broad range of length and timescales and utilizes all modes of heat transfer (convection, conduction, and radiation).

Few simulation tools have the validated capability to capture all of the physics required to accurately predict the thermal-hydraulic performance of a cooling system over the full range of operating scenarios required to demonstrate the safety and efficiency of a nuclear reactor.

Our advanced tools are able to simulate all aspects of coolant system performance, including transient multi-phase flow phenomena (boiling, cavitation, and condensation). They can simulate phenomena that operate across a broad range of length and timescales and utilize all modes of heat transfer (convection, conduction, and radiation). These solutions offer the ability to simulate system-wide behavior as well as capture the highest level of detail through its 3D computer-aided engineering (CAE) approaches such as finite element analysis (FEA) and computational fluid dynamics (CFD). Together they allow owners and operators to maximize the performance of existing cooling concepts and accelerate the design and licensing of innovative new concepts.
