Tomographic-PIV investigation of the 3D Separation behaviour of a micro-ramp controlled SWBLI

Micro-ramp vortex generators (or micro-ramps) have gained popularity as promising alternatives to boundary layer bleed for high speed flow-control applications. Micro-ramps generate a counter-rotating vortex pair which leads to a more separation resistant boundary layer. Furthermore, they modulate the size of the shock induced separation bubble...

The influence of fiber-matrix adhesion on the linear viscoelastic creep behavior of CF/PPS composites

The influence of fiber-matrix adhesion on the linear viscoelastic creep behavior of as received and surface modified carbon fiber (AR-CF and SM-CF, respectively) reinforced polyphenylene sulfide (PPS) composite materials was investigated. Short-term tensile creep tests were performed on ±45° specimens under four different isothermal condition;...
