Аннотация

Pressure drop and heat transfer of a fixed bed with different submerged tube bundles were measured over a wide range of Re-numbers. One essential parameter for calculating the pressure drop is the voidage. A correlation is given to determine the voidage in dependence of particle diameter and tube pitch. Then a model is presented which allows the calculation of the pressure drop in good agreement with the experimental data. In the second part experimental Nu-numbers for overall heat transfer between tubes and fluid are compared with calculated values. By adapting correlations taken from literature we got good agreement between measured and calculated values.
