Flow Viz
Heat/Mass Transfer

In this section we offer a brief overview of the experiment, the types of measurements made and the equipment used.

The fluid flow in a turbine engine is a combination of many complicated flows involving inpingement, boundary transition, separation, film cooling, wakes, tip leakage and secondary flows. The flow visualization and the naphthalene mass transfer technique are the main tools used extensively in the heat/mass transfer labs here.

The advantage of mass transfer technique is that the local detailed transport information can be easily acquired in a test. There is no conduction and radiation effect. Based on heat and mass transfer analogy, the mass transfer data can be readily converted into the heat transfer data with more local information about flow separation, transition and vortex flows.
