1. On focusing of strong shock waves
Sammanfattning : Focusing of strong shock waves in a gas-filled thin test section with various forms of the reflector boundary is investigated. The test section is mounted at the end of the horizontal co-axial shock tube. Two different methods to produce shock waves of various forms are implemented. LÄS MER
2. On focusing of shock waves
Sammanfattning : Both experimental and numerical investigations of converging shock waves have been performed. In the experiments, a shock tube was used to create and study converging shock waves of various geometrical shapes. Two methods were used to create polygonally shaped shocks. LÄS MER
3. Large eddy simulation of transonic flow with shock wave/turbulent boundary layer interaction
Sammanfattning : Large eddy simulations (LES) of shock wave/turbulent boundary layer interaction (SWTBLI) have been carried out. The flow configuration was that of transonic flow over a bump with inlet Mach number 0.75 and maximum Mach number 1.27. LÄS MER
4. Electron Heating and Acceleration at Earth’s Collisionless Bow Shock
Sammanfattning : Cosmic rays are ultra-relativistic particles traveling near the speed of light permeating the galaxy. Collisionless shock waves with their ubiquity throughout the universe and excellent capability of accelerating charged particles offer an explanation to the origin of cosmic rays. LÄS MER
5. Shock wave effects on the vascular endothelium
Sammanfattning : A shock wave is a pressure wave with high amplitude and a velocity above sound. Man is exposed to shock waves (SWs) in connection with trauma, e.g. explosions and high-energy missiles and medical treatments such as extracorporeal lithotripsy (ESWL). LÄS MER
