of1806中的epsilonWallFunction是否合并了LowRe的模型?

我在epsilonWallFunction中的calculate()定义中发现了如下代码:
if (lowReCorrection_ && yPlus < yPlusLam_) { epsilonc = w*2.0*k[celli]*nuw[facei]/sqr(y[facei]); Gc = 0; }
这是对yPlus是否处于粘性层进行了判断,并且公式也和粘性层的epsilon计算公式对应。而且我还find了一下epsilonLowReWallFunction,发现没有找到。是否是讲epsilonWallFunction和epsilonLowReWallFunction两个合并了呢?

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
