抄録: | Some experiments were carried out to develop the flow pattern and the mixing processin upper layer and middle layer flows under various hydraulic conditions.It was clarified that the velocity and temperature profiles in upper layer flow condit-ions could be represented by a well known log linear or log law like as those of windfield near the ground. It was found that the boundary layer of water temperature deve-loped in main flow direction as on a solid wall.Concerning the middle layer flows, many interesting phenomina were found as follows.Main flow region is formed between the main thermocline and the sub-thermoclinenear the free surface except near the upstream and downstream end of the experimentalchannel. The maximum velocity is occurred at just a half point of middle layer zonewhere the mixing is more active than in other region, and the velocity profile isanalogous to Gaussian curve decided by the depth of the midde layer. Moreover, themixing process of the sub-thermocline region is considered from a conceptual model. |
