Jun 30, 2024 · 467. By Dave Philipps. Photographs by Kenny Holston. June 30, 2024. David Metcalf’s last act in life was an attempt to send a message — that years as a Navy SEAL had left his brain so damaged ...
6 days ago · Experimental results for 25-mm and 51-mm rotating detonation rocket engine combustors. Shock Waves is dedicated to presenting and discussing new findings in fields associated with shock and detonation phenomena. Caters to physicists, engineers, ...
5 days ago · The transmission velocity of the shock wave in the oil was calculated to be approximately 1400 m/s, which is consistent with the speed of sound in the liquid, based on the distances between the sensor and the discharge centre (15 and 37 cm). At 69 μs, the diameter of the arc channel continued to expand, and the shock wave front propagated outward.
22 hours ago · Shock tubes are used to study high speed gas dynamics by generating a shock wave to rapidly heat and compress a test gas. This present work investigates the influence of real gas effects on the run time in a shock tube using computational fluid dynamics simulations. The shock wave dynamics of CO 2 is studied at gaseous state, supercritical ...
Jun 20, 2024 · extracorporeal shock wave therapy (rESWT) and custom orthoses were suggested. WHAT THIS STUDY ADDS ⇒ In patients with plantar fasciopathy who received advice and customised foot orthoses, this randomised controlled trial (RCT) showed no additive effects of rESWT, sham-rESWT or a standardised exercise programme over
Jun 11, 2024 · Fast-response transducers and schlieren visualization with a high-speed camera were employed to capture dynamic pressures on walls and shock interaction patterns, respectively. The results demonstrate that the characteristics of shock train motion can be strongly affected by throttling position.
Jun 11, 2024 · In this study, we carried out a CFD numerical simulation of shock wave monitoring. We also developed a shock wave generator with a 2 L gas storage tank volume and a shock wave monitoring system with a 1 M shock tube length to monitor the velocity and pressure of the shock waves generated.
