Abstract

The heated surface jet discharged into a bay which is connected to a larger body of water through a strait may experience bifurcation in the bay and stratification in the strait. The combined effects of bifurcation and stratification may lead to a substantially greater rise in temperature than the rise expected in case of unrestricted receiving body of water. In this study, the behavior of heated effluents discharged into bays with a restricted access to a large body of water is scrutinized experimentally by the help of a scaled physical model.Dimensional analysis leads to a new dimensionless parameter Ar, area restriction parameter, on which the difference between the excess temperatures at the inlet of the strait for restricted and free receiving mediums, Δ(ΔT/ΔT 0 ) is shown to be strongly dependent.

海峡对小海湾水热性能的影响

通过海峡与更大的水体相连的海湾排放的加热表面射流可能在海湾中发生分岔，在海峡中发生分层。分岔和分层的综合影响可能导致比不受限制的接收水体所预期的温度上升大得多的温度上升。在本研究中，通过比例物理模型的帮助，实验研究了排放到受限制进入大面积水体的海湾的加热废水的行为。量纲分析得到了一个新的无量纲参数Ar，即面积限制参数，该参数与海峡入口受限制介质和自由介质的过量温度之差Δ(ΔT/ΔT 0)有很大关系。

期刊介绍： The scope of Teknik Dergi is naturally confined with the subjects falling in the area of civil engineering. However, the area of civil engineering has recently been significantly enlarged, even the definition of civil engineering has somewhat changed. Half a century ago, engineering was simply defined as “the art of using and converting the natural resources for the benefit of the mankind”. Today, the same objective is expected to be realised (i) by complying with the desire and expectations of the people concerned and (ii) without wasting the resources and within the sustainability principles. This change has required an interaction between engineering and social and administrative sciences. Some subjects at the borderline between civil engineering and social and administrative sciences have consequently been included in the area of civil engineering. Teknik Dergi defines its scope in line with this understanding. However, it requires the papers falling in the borderline to have a significant component of civil engineering.
