3
- MACH - NUMBER TABLES
- THE MACH NUMBER RELATIONS, EXPRESSED IN EQUATIONS (3.16) TO (3.19) ARE FREQUENTLY EMPLOYED IN THE ANALYSIS OF COMPRESSIBLE FLOWS.
- THEIR REPEATED ALGEBRAIC SOLUTION CAN BE TIME CONSUMING.
- FOR THIS REASON, THEIR NUMERICAL SOLUTIONS ARE AVAILABLE IN THE FORM OF TABLES OF P/PO, /O, AND T/TO VALUES FOR DIFFERENT VALUES OF M.
- SEE pp 696-698 IN F M WHITE AND ALSO THE DATABOOK
3.3.3 ISENTROPIC FLOW THROUGH VARIABLE AREA DUCTS.
- FOCAL POINT : INTERNAL, COMPRESSIBLE AND
ISENTROPIC FLOWS THROUGH DUCTS OF VARIABLE CROSS-SECTIONAL AREA.
- THE FLOW IS ASSUMED TO BE ONE-DIMENSIONAL
OBJECTIVE : TO DETERMINE HOW THE
FLUID VELOCITY U, TEMPERATURE T AND PRESSURE P, VARY WITH THE DUCT CROSS-SECTIONAL
AREA.
