摘要
本文依据等速两向流的假定,应用动量定理,在掺气临界工况条件下导得掺气临界工况方程。通过计算表明,掺气临界工况的计算值与试验值趋势一致。本文还进行了折流器对泄流能力以及侧空腔长度的影响等试验。最后,提出了突扩门槽门室通气孔的通气量估算式。
In this parer, based on the hypothesis of two dimensional uniform flow, a state epuation of the flow aeration is derived by momentum law under the critical condition of the flow aeration, Calculating the critical working state equation of the flow aeration, it is proved that the results are in good agreement with the tendency of the model tests. The jet deflector experiments has been made to determine the relationship between the size of the jet deflector and discharge capacity, as well as the effects of the length of the side hollow. Finally, the equation of the air discharge throuth the air vent of the sudden expansion gate slot is presented by analyses of the test data.
