【Abstract】 The local flow and heat transfer process in the fixed bed directly affect the reaction yield and the safety of the reactor structure. The research on the internal reaction characteristics of the fixed bed reactor has been a challenging problem. The methods of measurement and mathematical simulation are widely used in the study of the internal pressure field, temperature field and flow characteristics of the reactor. This paper reviews the progress of the computer simulation of the internal field distribution of the fixed bed reactor, and discusses the research contents and research methods at the macro, meso and micro scales, and gives some useful advises to the further study.更多还原
