概要 | The association of enormous amounts of energy proximate to hydraulic structures, like spillways, downstream of draft tubes, etc., which might be harmful to environment , has prompted the researcher to... consider this occurrence to dissipate this excess energy. Due to natural occurrence, hydraulic jump unavoidably re duces incoming flow energy. Most of the researchers considered hydraulic jump characteristics to be the function of inflow Froude number but i n this research, the effects of incoming Reynolds number (Re1) is introduced first time in a sloped channel jump and all the correlation are formed while taking into account the influence of Re1Re1, inflow Froude number (Fr1) and Channel slope (θ). The experiment was performed in the sloped channel (0 0^0, 2^0, 4^0 and 6^0) in an open channel flow test setup and eight experiments are designed and performed and collected 57 data for each channel slope. Regression analysis was utilised after using Buckingham's theorem to make all the variables dimensionless to generate correlations. Moreover, error analysis was carried ou t, and all created correlations were compared to correlations that had already been developed. The depth ratio (d d_2/d _1) increases by 34.8 34.85%, relative length (L_j/d_ 1) decreases by 18.9 18.91% and energy loss (E_L/E 1) increases by 63.6 63.62% for 6 60 channel slope as comp ared to the classical jump. The R R2 value of developed correlation for d_2/d_1, L_j/d_1, L_j/d_1 (in terms of d_1/d_2) and E_L/E_1 was 0.98, 0.975, 0.98 and 0.99 respectively which shows the efficacy of the entire developed model.続きを見る |
