Numerical Simulation of Hydraulic Jumpby Anand Raman,
M. Hanif Chaudhry,
Abstract: Hydraulic jump is numerically simulated by solving the laterally-averaged governing equations. The governing equations are derived for two-dimensional flow by laterally averaging the time averaged three-dimensional Navier Stokes equations in conservation form. The MacCormack explicit finite-difference scheme is employed to solve the system of governing equations. To enhance applicability, the governing equations are solved in curvilinear computational coordinates. Unlike other models, the present model does not employ the hydrostatic pressure approximation. However, the turbulent stresses, viscous stresses and momentum dispersion stresses were neglected. The numerical results are compared with the experimental data. Agreement between the computed and measured results is satisfactory.
