Temperature Distribution Predictions
Cross Sectional Views of Electric Heat Exchanger
Using CFD simulation for thermal performance prediction can dramatically reduce the amount of physical prototypes and test work required which will either reduce product development lead times, the cost to the client or enhance the quality of the product received by the client.

In order to help validate the performance of a be-spoke electric heating solution, as quickly as possible, from a demanding client specification, Vulcanic commissioned 80/20 Engineering to provide some additional consultancy assistance to their design team in Dereham, UK. Shown below is a brief summary of a CFD study carried out on a concept electric heat exchanger element.
Vulcanic – Case Study Work
(Some of the case study results shown)
Managing the gas flow paths within and around the heat exchanger tubes efficiently can substantially reduce operating temperatures and eliminate the likelihood of ‘hotspots’. Using CFD simulation, a complete three-dimensional thermal map can be obtained from any operational conditions and once a concept is selected further simulations can be carried to refine the idea or test the impact of manufacturing or material specification constraints.
CFD techniques also helped design engineers at Vulcanic really understand why the heating element has certain behavioral characteristics. The fluid flow paths could be easily visualized and re-circulation, or dead zone areas, better understood that reveal performance issues such as hotspots. This then facilitates design change that balances or evens out the heat transfer process.
