A parametric study of effect of forebody shape on flow angularity at Mach 8 [PDF]
Flow angularity and static pressure measurements have been made on the lower surface of nine forebody models that simulate the bottom forward surface of a hypersonic aircraft. Measurements were made in an area of the forebody that represents the location

Investigation of the isolator flow of scramjet engines
, 2014 This thesis focuses on the isolator of a Scramjet engine. The influence of wall and total temperature on the flow field is investigated with the help of different wind tunnel models. The wall temperature is varied from 300 K to 1000 K and the total temperature between 1150 K and 2200 K. The free stream Mach number is Ma∞ = 7.5.
