主动冷却基板（ACS）是一种微机电系统（MEMS）装置，其将合成射流概念实施到印刷线路板（PWB）中以增强热管理。本文提出了一种求解合成射流流体力学和传热问题的数值方法。Fluent是一个计算流体动力学（CFD）软件包，用于执行三维（3-D），非定常和双精度模拟。湍流模型选用大涡模拟（LES）。模拟结果与实验数据吻合较好。为合成射流主动冷却基片的未来设计提供了一个数值预测模型。
An active cooling substrate (ACS) is a microelectro mechanical system (MEMS) device which implements the synthetic jet concept into printed wiring board (PWB) to enhance thermal management. This paper presents a numerical approach to solve the synthetic jet fluid mechanics and heat transfer problem. Fluent, a computational fluid dynamics (CFD) package, is utilized to perform the three-dimensional (3-D), unsteady, and double precision simulations. The large eddy simulation (LES) is selected as the turbulence model. The simulation results are consistent with the experimental data. A numerical predictive model is developed for future designs of synthetic jet based active cooling substrates.
