Among the many problems which face airframe manufacturers, cooling is certainly one of the most important, particularly as a special watch must be kept on the type of solution to be adopted, since the lowest fuel penalty must be incurred in flight.

Abstract Laser repetitive pulse heating is one of the research fields in laser heating of engineering surfaces. The effect of assisting gas jet on the laser heating process is usually omitted in the previous studies. The present study examines the gas jet assisted laser repetitive pulse heating of steel surfaces.

In the last chapter, induction was used for heating large masses of metal, where the aim was a uniform temperature throughout. There, the possible high in tensity of induction heating was limited by the rate at which the heat could be conducted away from the surface. Surface hardening makes use of this 'disadvantage'.

Heat recovery without heat transfer surfaces
Journal of Heat Recovery Systems, 1983Abstract Most heat recovery systems involve heat transfer surfaces. This fact means high initial investment, high maintenance costs and efficiency decrease because of the fouling of the heat transfer surfaces. This article describes the working principles of a surface-less heat recovery system, the mathematical approach to treat such systems and ...
