Research Activities
The visualization of heat/mass transfer and fluid flow is an important technique for improving energy systems.
1. Development of Temperature Sensitive Particles
Temperature sensitive particles (TSPs) can be used to simultaneously measure velocity field and temperature in fluids. Before the development of TPS, there was no technique to measure temperature and flow field in a gas flow. TSP measurement has quite a high time resolution because a high-speed camera and a pulse laser with a very high repetition rate are used. This technique can be used to develop and improve an advanced heat exchanger as well as for other practical applications.
2. Laser Induced Fluorescence
Laser induced fluorescence (LIF) can perform highly accurate measurements of pH/temperature distribution in liquids, even under high-pressure conditions. For example, it can measure the solubility of CO2 under a deep-sea condition.
