Unformatted text preview: ork as well are seperated flows where the angle of attack gets so high that a large wake region is generated in which viscous effects are important. Blunt bodies also make large wakes with substantial regions which must be handled with the tools appropriate to viscous flows. Most of this course will deal with inviscid flows. Toward the end of the course we will return to viscous flows. We will develop equations for the thin boundary layers, and also look at the separated flow cases. Incompressible vs compressible flows The Mach number M or Ma = V/a where a is the speed of sound in the fluid Where γ and R are properties of the gas (1.4 and 287 J/kg‐k for air at STP) Based on free‐stream Mach number . The local Mach number may be higher. Incompressible – liquids and < 0.3 No compr...
