Effects of cylindrical-obstacle spacing on granular shock wave interactions in gravity-driven flows

Journal of Rock Mechanics and Geotechnical Engineering
Hazardous geophysical granular flows, such as debris flows and rock avalanches, can exert intense impact forces on obstacles and threaten downstream structures located in their paths.

Simulation of The Effects of Valve Timing Misalignment on Performance in Spark Ignition Engines

Engineering Perspective
Engine performance can be improved by changing the valve opening (or closing) timing without any cam profile changes. In this study, a simple simulation model was created for valve timing misalignment, which is an assembly defect in the engine.
