Job description

The Centre for ECO2 Vehicle Design is now seeking a Post Doctor within the field of modelling transient cooling in vehicles.

In passive convective cooling of electrical components on vehicles, both the temperature of the component to be cooled and the cooling effect of the flow are often coupled through the operational characteristics of the vehicle. This interaction is transient and load cycle dependent, as the temperatures of the component and the flow vary continuously, and so are not stationary for a given vehicle speed. In addition to this transient coupling of heating and cooling, there is also a spatial coupling when components are placed downstream of another. As the air cools one component, its temperature rises, and it becomes less effective as coolant for subsequent downwind components.

The project will focus on developing models that can be used to explore transient effects and dynamic coupling between the heat source and sink within the context of rail vehicle operation. First, a model for the coupling the heat generation and convective cooling during vehicle operation will be developed. This will be done using available data for specific components of interest and operational loads cycles. Then, the dynamics of this coupling will be explored to identify under which conditions vehicle motion cooling cannot provide sufficient cooling.

This could be used, for example, to avoid driving behaviours that lead to heat build-up. The combination of multi-stage sequential cooling will also be explored to understand under what environmental and operational conditions certain components may be at risk of overheating. This research will improve planning layouts of components and/or thermal management in novel vehicle constructions.
