HEAT TRANSFER EXPERIMENTS IN DISPERSE SYSTEMS AT HIGH TEMPERATURES
摘要
The paper deals with the results of experimental investigations at high temperature processes in disperse
systems. The heat transfer was determined
by a model reaction viz. the thermical cracking of calcium carbonate. A short description of experiments and a survey on the modelling and calculating
is given. As a result a correlation between the Nu- and the Re-number was found. This correlation is in accordance with the heat transfer by spheres concerning
the exponent of Re-number. An important difference however exists in the coefficient of Re-number in consequence of the high density of heat
transfer. A quotient of the heat conductivities for the gas stream and the particles surface equalized the
results.
