Is there really a relationship between the exhaust temperature of a reciprocating machine and the specific gravity of the medium?
Thread Content
As the title says. I don’t think it matters; it’s probably related to the insulation coefficient of the medium.
Is there no one to help clarify this? The questions I asked were so simple that they exhausted my hands!
Related to exhaust temperature, pressure ratio, adiabatic coefficient, and inlet temperature
Back in a certain year, a test was conducted in which nitrogen was filled into the hydrogen compressor. As a result, the exhaust pressure, temperature, and vibration all increased. Logically, the adiabatic indices of nitrogen and hydrogen are similar, so shouldn’t the pressure ratios be the same? So I think media with different densities will affect different compression ratios, which in turn affects the exhaust temperature
The conclusions drawn from our on-site tests are as follows: different specific gravities result in different outlet temperatures. For example, when hydrogen is used for circulation during normal production, the temperature is lower; whereas when nitrogen is used for circulating to purge the reaction system, the outlet temperature rises significantly
There is a relationship: the compressed medium has a higher density, which results in a higher exhaust temperature, due to the large molecular weight of the medium
Of course it has an impact; with a large molecular weight, the impact kinetic energy is naturally high
What is the adiabatic coefficient related to? The original poster can compare and calculate to find out
