Main-variable Correction of Energy Balance Equations in Zone Method
HU Zhangmao, LI Benwen, CHEN Haigeng
CHINESE JOURNAL OF COMPUTATIONAL PHYSICS    2009, 26 (3): 431-436.   DOI: 10.3969/j.issn.1001-246X.2009.03.014
Abstract337)      PDF (306KB)(1421)      
With analysis on physical characteristics of heat transfer in zone method,mathematical-physical characteristics are considered for main-variable correction in zone method.Detailed principle and solution procedure of main-variable correction method is introduced. It is compared with other methods with a typical example.It shows that the main-variable correction method is more reliable and applicable.

EVALUATION OF RADIATIVE DIRECT EXCHANGE AREAS IN A NON GRAY MEDIUM
Nie Yuhong, Chen Haigeng, Yang Zekuan
CHINESE JOURNAL OF COMPUTATIONAL PHYSICS    1997, 14 (3): 345-348.  
Abstract231)      PDF (163KB)(1096)      
Wide band mold and its modification are used to simulate the radiative properties of non-gray gases, and they are combined in zone method to calculate the surface surface radiative direct exchange areas for a non gray medium. Results show that the modified wide band model can successfully describe the properties of non gray gases, and can be easily combined with zone method.

THE CALCULATION OF RADIANT TOTAL EXCHANGE AREAS IN NONGRAY GAS
Nie Yuhong, Chen Haigeng, Yang Zekuan
CHINESE JOURNAL OF COMPUTATIONAL PHYSICS    1997, 14 (2): 202-206.  
Abstract248)      PDF (189KB)(1183)      
The uniform deterministic discrete emission method and wide band model are combined to calculate the total radiant exchange areas for a two dimensional enclosure filled with nongray gas.The results show that the uniform discrete deterministic emission method can be used to a nongray medium.At the same samples the uniform discrete deterministic emission method is better than Monte Carlo method.
