Mathematical Model and Numerical Simulation of Aluminum Casting and Solidification in Magnetic Fields with Allowance for Free Surface Dynamics
A complex mathematical model of aluminum casting and solidification in a variable electromagnetic field is constructed. The model is based on the solution of magnetohydrodynamic equations and the VOF method. Test results ...
Mathematical modeling of low-frequency pressure fluctuations in hydroturbine ducts
The results of the modeling of unsteady three-dimensional flows in the hydroturbine ducts of two high-head hydroelectric stations are presented. The flow structure behind the turbine wheel is analyzed and its effect on the ...
