PRACTICAL DESIGN OF APPURTENANCES IN SWEPT HYDRAULIC JUMP BASINS

摘要

A systematic methodology of utilizing preliminary design of appurtenances in swept jump basins is discussed. The methodology introduced herein replicates the practical flow scenario occurs in swept jump basins. Estimation of the swept distance of the jump toe associated with the expected maximum Froude number and the limited tailwater depth is introduced. A degree of forcing and a minimum Froude number, below which the submerged flow takes place, are suggested as the main criteria in measuring the design effectiveness of different appurtenances alternatives. A physical model is introduced for further illustration of the suggested design methodology. The basin length of the minimum tailwater depth scenario is introduced and compared with the real length scenario. Empirical equations are introduced for the tested physical model. The minimum tailwater depth scenario is introduced to check the stability of the forced jump for real basin parameters.
