Simulation achievement of lab-scale formations with high geotemperature gradient

Autor: Deqian ZHANG, Haiyan LEI, Chuanshan DAI

Publikováno v: Shuiwen dizhi gongcheng dizhi, Vol 50, Iss 1, Pp 152-157 (2023)

The heat exchange between geothermal wells and surrounding formations is important to the heat production of geothermal wells. Due to the difficulty in arranging measurement points around geothermal wells in real engineering, it is hard to verify the

Flow pattern analysis around a solid cylinder with both porous and water rings in porous media

Autor: Lin ZHU, Haiyan LEI, Fei MA, Chuanshan DAI

Publikováno v: Shuiwen dizhi gongcheng dizhi, Vol 48, Iss 4, Pp 25-31 (2021)

The flow field around a solid cylinder with both porous and water rings embedded vertically in an infinite large porous media is analytically simulated. The Brinkman model are applied for both the internal porous ring and external infinite large poro
