Problem Definition
To find out pressure drop of pressure regulator valve for various opening conditions and various steam properties.
ChallengesPressure drop as given below,
| Static Pressure in bar | Full open, Superheated Steam Prop. @11 bar with 2266 kg/hr | Full open, Dry Saturated Steam Prop. @11 bar with 1133 kg/hr | Half open, Superheated Steam Prop. @16 bar with 2266 kg/hr |
|---|---|---|---|
| Inlet Pressure | 14.80 | 0.20 | 14.60 |
| Outlet Pressure | 3.01 | 0.20 | 2.81 |
| ΔP (bar) | 29.40 | 0.20 | 29.20 |

Problem Definition
To find out pressure drop in an air intake duct with & without filter
ChallengesHexahedral mesh at bends
ConclusionsTotal pressure drop of the system in case of filter is increased by 40% than without filter

Problem Definition
- To find out pressure drop from inlet to each vent
- Total pressure drop
Handling heavy cell count of around 9 million
ConclusionsBased on simulation results of pressure drop and mass flow at each vent, appropriate pressure /mass flow of air is maintained at inlet.
