摘要
The convective heat transfer coefficient and pressure drop in ceramic foam structures are measured. Cordierite foams with 10, 20, 30 und 50 pores per inch (PPI) at empty tube velocities (of air) at 0.5 to 14 m/s are investigated. The convective heat transfer between fluid and substrate is described well within this velocity range by means of the assumption Nu = c . Re(m) . Pr1/3. The experimental method developed to obtain the values of c and m is described. The data thus gained are discussed in view of an application of ceramic foams as catalyst supports and are compared with data of conventional parallel channel monoliths mentioned in the literature.
