An analysis of a tube‐wall reactor with varying volume is considered under turbulent flow conditions for the case in which both the kinetic and diffusional resistances are important. The implicit molar flux expression is approximated by three successive approximations and the mass and energy balances are combined to obtain a single explicit design equation. This equation takes the form of a simple numerical integration which requires only physical and chemical properties of the inlet gas and reactor operating conditions. The method also predicts the temperature and heat flux along the reactor length. Comparison of the model predictions with a limited number of previous experimental results is good.
