A lifted airfoil at supersonic speeds, in general, generates shock waves (therefore, wave drag) through two fundamentally different mechanisms.
That generates shock waves — essentially small sonic booms — that greatly increase air resistance, requiring more fuel to maintain speeds.
In a methane explosion event, the explosion propagation can quickly reach supersonic and thus generates shock wave.
The researchers devised a mathematical model, which revealed that as soon as any fault begins to rupture, it generates shock waves that race through the rock ahead of the rupture.
But many artists say that generating shock remains the duty of anyone who aims to reflect the real world back at itself.
The testing employed an efficient, cost-effective new method that has replaced older seismic mapping techniques that used sledge hammers, movable weights and even explosive charges to generate shock waves.
Having banks in models would generate shocks from within the system.The world's big central banks are interested in these new ideas, although staff economists are reluctant to abandon existing "industry-standard" models.
Peter Freeman, an owner of Brooklyn Farmacy and Soda Fountain in Carroll Gardens, said Mr. Bloomberg's new platform was an attempt to generate "shock and awe" among New Yorkers who don't think enough about calorie counts.
As usual, it was all about getting laughs or generating shock value.
Depth profile of micro-hardness shows the impact of laser generated shock wave up to 1.2 mm from the surface.
