在头文件找到了描述:The low-Re correction is activated by setting the entry lowReCorrection to 'on'; in this mode the model switches between laminar and turbulent functions based on the laminar-to-turbulent y+ value derived from kappa and E. When the lowReCorrection is inactive, the wall function operates in high-Re mode.可能是在constant文件里使用这epsilonWallFunction的时候能够选择打不打开LowRe
