Ansys Fluent: False Gear Pump With Dynamic Mesh: Setup
Simulation of a 2D gear pump using the dynamic mesh method. In the video you can see that the gears do not touch each other, obviously this is not physically possible, hence what i mean by "false".
The contents of the UDFs are:
UDF1:
#include "udf.h"
DEFINE_CG_MOTION(gear_1_new,dt,vel,omega,time,dtime)
{
real t = CURRENT_TIME;
NV_S (vel, = , 0.0);
NV_S (omega, = , 0.0);
omega[2] = 60.0*(1-0*exp(-500000.0*t));
}
UDF2:
#include "udf.h"
DEFINE_CG_MOTION(gear_2_new,dt,vel,omega,time,dtime)
{
real t = CURRENT_TIME;
NV_S (vel, = , 0.0);
NV_S (omega, = , 0.0);
omega[2] = -60.0*(1-0*exp(-5000000.0*t));
}
These are to set the motion of both gears.
