Abstract:

A critical analysis of the methods used to determine the overall heat transfer coefficient is carried out. The measurement of the axis temperature is recommended for the evaluation of the local value of the coefficient; an asymptotic value is obtained for bed lengths greater than a certain minimum. The different relationships that can be established between the heat transfer parameter of the pseudohomogeneous one-dimensional model and the basic parameters are established. The best agreement with numerical simulations is obtained for the equation derived via the heterogeneous one-dimensional model. A comparison with experimental results validates both the equation proposed and the correlations used for the evaluation of the basic parameters. © 1986.
