Influence of Brine Flow on Heat Exchange Coefficient of Frozen Pipe

With the progress of science and technology,the control frozen technology has been proposed in the field of freezing shaft project.Heat exchange coefficient of the frozen pipe is affected by various factors,including soil property,freezing pipe diameter,the space between holes,freezing time,brine temperature and flow.The relationship between the flow and heat the exchange coefficient of the frozen pipe was analyzed,and it is concluded that adjusting the flow in pipe can change its heat transfer coefficient,to achieve effective control of the freezing process,and provide a reference for the future implementation of the freeze control technology.
