抄録

This paper reports a numerical study for a singl e shell and tube rea ctor of CO₂ methanation with a 1.5 m long reaction zone. A new conjugate heat transfer solver is developed based on the open-source OpenFOAM code. The newly developed solver solves the heat transfer problem as well as the reactions happen in the gas phase. The reactor is meshed with fully resolved gas, solid, and coolant regions , Two-temperature model is considered to solve the temperature of catalyst bed . The tube diam e ter is changed to investi gate the effect on the hot spot formation. The results show that the diameter of the tube is an important factor in determining the tem perature profiles of the catalyst bed as well as reacting gas. The peak t emperature of the hot spot was decreased from 980 to 770K with decreasing the tube diame ter from 32 to 14mm at a GHSV=3428h^-1.
