Determining the temperature of a fluid present in an engineering device or a production process is one of the basic measurements required for control or diagnostics purposes. In the majority of everyday engineering applications, the temperature measurement systems rely on simple methods such as distribution of thermocouples or other well-proven techniques. However, with the increasing complexity of the engineering devices and the current drive towards increasing the efficiency of energy conversion processes, the application of sensors that can measure temperatures at selected points and with only limited temporal resolution is insufficient for development of new products or their diagnostics within an R&D context. Here, Shi et al describe in detail the design of an experimental apparatus which enables the deployment of the Planar Laser Induced Fluorescence methodology in oscillatory flow conditions.
