摘要：
The effects of inlet velocity and original temperature on flow field and temperature field in a sensible heat recovery tube bundle of coke oven crude gas and the heat transfer behavior between coke oven crude gas and water cooling tubes were numerically simulated by use of user-defined functions based on Fluent 6.3 software. The results indicate that the coke oven crude gas flows around the tubes in the tube bundle and the wake flow eddy whose velocity is very low lies the in the back of tubes. The easier condensation zone for coal tar lies in the bake of the first row tubes and the bake or front of the others. It has the advantage to avoid coal tar condensation by increasing inlet velocity and original temperature of crude gas, at the same time the sensible heat recovery efficiency decreases and the average temperature increases at the tube bundle outlet under the same condition. © 2017, Central South University Press.
