Abstract
The desired technology for manufacturing light-weight components from metal alloys mostly aluminum and magnesium alloy
is Die casting. High pressure die casting requires the liquid metal to be forced at high speed and pressure through a metal pipe.
In our study, we seek to study Aluminum filling under high pressure in two different pipes, cylindrical and conical pipes. Two
cases are considered for the cylindrical pipe, when the pipe vertical and when the pipe in inclined at an angle of 450 with the
horizontal. The governing equations are obtained and the results are compared. The governing equations are obtained and
modeling is done using ANSYS FLUENT.
The results show that inclining the cylindrical pipe causes a shift in the oscillations and the inclined pipe has slightly lower
amplitude of oscillation implying a greater loss of energy due to the inclination. The inclined cylindrical pipe has higher
damping compared to the vertical cylindrical pipe. It is also evident that the conical pipe has higher oscillations than the
cylindrical pipe implying a greater loss of energy for the conical cylindrical.
