Abstract

Because of their effectiveness and adaptability, impinging jets have found their way into a host of applications ranging from cooling turbine blades, to heat management of electronic systems or even lowering the temperature of a hot cup of coffee in the morning. With constantly increasing demand for efficient and compact cooling systems in certain industries, such as the aerospace or electronics industries, variations on the textbook-setup of an impinging jet have been studied over the years. One such variation introduces a periodic disturbance into the jet that can have an effect on both the structure of flow and the thermal boundary layer at the target surface. In what follows is a short overview of studies having used pulsed jets, often in tandem with other modifications, to try and improve heat transfer. Special attention was also given to the methods by which the periodic disturbance can be produced since they involve setups of different levels of complexity and having different implementation costs.

脉冲冲击射流的传热:简要综述

由于其有效性和适应性，撞击式射流在许多领域都有应用，从冷却涡轮叶片到电子系统的热管理，甚至降低早晨一杯热咖啡的温度。随着某些行业(如航空航天或电子工业)对高效、紧凑的冷却系统的需求不断增加，多年来人们一直在研究教科书上关于撞击式喷气机的各种设置。其中一种变化会在射流中引入周期性扰动，对目标表面的流动结构和热边界层都有影响。以下是使用脉冲射流的研究的简要概述，通常与其他修改相结合，试图改善传热。还特别注意了产生周期性扰动的方法，因为它们涉及不同复杂程度的设置，并且具有不同的实现成本。
