是有关侧面加热的封闭腔内的自然对流湍流的~这段话是解释在下游Nu波动的原因~~希望能准确翻译下~谢谢
These large fluctuations are due to the large eddies generated in the downstream part of the boundary which result in altenative local thichening or thinning of the thermal boundary layer.There large eddies also result in an efficient mixing of the outer region of the boundary layer and to enhanced fluid transport from the downstream part to the corresponding facing upstream part of the opposite boundary layer. |
