Abstrakt

A mass transfer analogue technique has been developed which can be used to determine convective heat transfer coefficients rapidly and economically in internal geometries of complex shape. This analogue has been used for heat transfer measurements in models of power station steam headers in order that temperature distributions arising during "startup" conditions may be computed. A wide variation in heat transfer has been found to exist over the surfaces owing to the complex nature of the flow pattern. This flow pattern has been studied visually to determine the main features influencing heat transfer. Some progress has also been achieved using a computational technique to study the nature of the flow pattern, which should ultimately allow the heat transfer coefficients to be predicted directly.
