steady state throttling

From the below plots , simulations and flow analysis , it can be stated that

1.)Mass flow rate gradually decreases in the inlet whereas it increases in outlet till the steady condition is not achieved i.e. 0.065kg/s.

2.)Based on the simulations and analysis , the static pressure also decreases from 150,000 Pa to nearly at 120,639Pa at the inlet and total pressure remains constant 150,000Pa.

3.) At the outlet Vice versa happens , the static pressure remains same 100,000 pa and totaal pressure changes from 100,000 pa to 135602 pa.

4.)The average density , temperature and velocity at the inlet increases between 0 to 1000 cycles but then decreases till the steady state is reached .

5.) The average density decreases and increases alternatively as shown in the plot between 0-2000 cycle until the steady state is not reached i.e1.28 kg/m^3
