Thermal constraints impose limitations on the power capability of many electric motors and generators. However, inadequate data on ventilation air flows and convection heat transfer coefficients hamper the design process. Computational fluid dynamics

The swollen polymer technique is a method for measuring mass transfer coefficients under steady-state conditions. Heat transfer data can then be inferred by analogy, as with the more familiar naphthalene sublimation technique. The swollen polymer tec
