COMBINING POWER-LAW AND SURFACE-DRAG FLOW MODELS: A NEW APPROACH FOR IMPROVING ZONAL MODELS

Teshome Jiru, Fariborz Haghighat

Abstract: This paper presents the methodology for combining the power-law model (PLM) with the surface-drag flow model (SDM). The two types of combination explored were the direct and the indirect approaches. The direct combination of SDM and PLM has provided three different forms of zonal models: SD-PLM1, SD-PLM2, and SD-PLM3. The indirect combination gave the modified power-law model (MPLM). The predictions of the models were compared with each other and with experimental data for isothermal and non-isothermal cases. The MPLM has provided the best predictions of the recirculation in the standard zone.
