Flownex® SE determines pressure drop [flow] and heat transfer [temperature] for the connected components of a complete system in steady state and transient. So Flownex can be used to study heat transfer and fluid transients in e.g. motor cooling systems, electronics cooling panels, pumps or compressors, pipes, valves, tanks and heat exchangers.
Includes components to model the flow, heat transfer and control changes of thermal management systems for traditional automotive applications.
Includes air conditioning (vapour compression cycle) systems and components for air side and refrigeration side (phase change physics, component characteristics)
Available components: Pumps, heat exchangers, piping, valves, custom components such as the water block, control valve / thermostat
The thermal management of electric vehicles becomes more complex, including evaluating control philosophy during different operating conditions.
Flownex has a control system library to simulate system response to changes in the flow and heat transfer. It enables to simulate battery temperature changes as well as environmental changes and monitor how the system would react.
