Hai,
In the process developing new compressor, we changed the pistom material from cast-iron to aluminum.
In order to calculate the design parameters of the piston and accordingly choose the piston ring, I thought of doing some analytical or finite element study.
I know the procedure for calculating the compression heat.
But from the temperature of the fluid under compression, I want to calculate the temperature of piston solid surface. Is any text book or web-site is there for empirical relations for calculating the heat transfer co-efficient.
If so,please forward the same. Between the cylindrical surface of the piston and piston ring and cylinder bore the lubrication is provided.Is there any empirical heat transfer co-efficient correlation for these lubricated surfaces also?
With regards,
elogesh
