Drag of a bluff body is highly affected by pressure drag more than skin friction drag, whereas the relation is opposite for a streamline body, because of its projected area in x-direction.

Essay The Fluid Dynamics Of Bluff Bodies. vibrations, or more commonly known as vortex-induced vibrations (VIV’s), exerted on bluff bodies. Due to the production of vortex shedding beyond bluff cross sections, an alternating pressure distribution produces periodic fluctuations in lift and drag forces on the surface of the body; generating a vibrational response.

Record the time when the reaction is finished in Table 2 of the Data section, along with the final volume of air in Table 1.
Remember to read it at eye-level and measure from the bottom of the meniscus. The cylinder shown has a volume of 54π cm3. In a similar cylinder, the dimensions have been doubled. What is the ratio of the volumes (small to large).
- Particle rings/shells/cylinders dispersed by the radial impulsive loadings ranging from strong blast waves to moderate shock waves form a dual coherent jetting structure consisting of particle jets which have different dimensions.
In both circumstances, the primary jets are found to initiate from the inner surface of particle layers and propagate through the thickness of particle layers, which Author: Kun Xue, Xiaoliang Shi, Kaiyuan Du, Haoran Cui.

The Design and Construction of a 20" x 20" Mach Blowdown Wind Tunnel to Characterize the Lift and Drag of Irregularly Shaped Fragments View/ Open etd Author: Christopher Whitford Larson.
My understanding is that the blast wave and not the speed of the winds is what would wreck infrastructure. posted by zarq at AM on Ma [ 3 favorites ] Speaking of Dan Carlin, I recall him talking about one of the suggested designs for what is now known as “The Football”, i.e., the device with which nuclear weapons can be.
When this happens, the force applied to the piston by the expanding gas starts to diminish, and the power stroke is rapidly nearing its end. This usually happens at degrees ATDC. Ideally, the gas has all been consumed by this time. This concludes a normal power stroke which had no pre-ignition and no detonation.
Example: If I know my SAC Rate is and I plan to dive to 66 feet (ie: 3 atmospheres of pressure), I would multiply by 3 to get an air consumption rate of PSI/min at 66 feet. Determine how long your scuba tank will last at your planned depth.
Throughout this book it will be assumed, inconvenient though that assumption may occasionally be, that the reader has progressed to at least a superficial knowledge of the manner in which a piston-type internal combustion engine - with particular reference to those operating on the two-stroke cycle principle-converts quantities of fuel and air into useful power delivered at the end of its.

The shock wave and combustion wave are coupled and in a gas-air cloud the detonation wave will typically propagate at m/s and result in overpressures of bar.
Most vapour cloud explosions offshore would fall into the category of deflagrations. This process is completed within less than the first millisecond and it takes place after the formation and radial expansion of the cylindrical shock wave that will be discussed shortly.
