SEMI-EMPIRICAL MODELS FOR TRANSIENT HEAT TRANSFER OF PIN-FIN HEAT SINKS SUBJECTED TO NON-UNIFORM HOT JET HEATING

摘要：

Jet blast deflectors (JBDs) are safety devices used on aircraft carriers to deflect aircraft exhaust upward to protect people and any equipment behind the JBD. As the cooling of the JBD is typically characterized by three-dimensional and transient heat transfer in complicated structures, JBD design using conventional CFD simulations is time-consuming and exhaustive. To address the issue, we present two cost-effective semi-empirical models, a fin analogy model and a porous medium model, to predict the heat transfer of forced air convection in pin-fin heat sinks under non-uniform heating of hot jet. Both models are experimentally validated, with excellent agreement achieved.
