Hodgson Number

Hodgson number is proportional to { (time constant of system) / (period of pulsation) } and is used in momentum transfer in general and unsteady pulsating gas flow calculations in particular. It is normally defined in the following form :

 

Hodgson Number

 

Where:

delta-P

=

Pressure drop

fr

=

Frequency

p

=

Avg. static pressure

q

=

Avg. volumetric flowrate

V

=

System Volume
