Shock Tube as an Impulsive Application Device

Abstract

Current investigations solely focus on application of an impulse facility in diverse area of high-speed aerodynamics and structural mechanics. Shock tube, the fundamental impulse facility, is specially designed and calibrated for present objectives. Force measurement experiments are performed on a hemispherical test model integrated with the stress wave force balance. Similar test model is considered for heat transfer measurements using coaxial thermocouple. Force and heat transfer experiments demonstrated that the strain gauge and thermocouple have lag time of 11.5 and 9 microseconds, respectively. Response time of these sensors in measuring the peak load is also measured successfully using shock tube facility. As an outcome, these sensors are found to be suitable for impulse testing. Lastly, the response of aluminum plates subjected to impulsive loading is analyzed by measuring the in-plane strain produced during deformation. Thus, possibility of forming tests in shock is also confirmed.

Computational Study of Miniature Tube for Biomedical Application

“…A user-defined function (UDF) has been adopted to divide the computational domain into the driver and driven sections for initialization in the present simulation. The diaphragm is supposed to burst instantly at time zero because the diaphragm's bursting is not the main priority (Nanda et al, 2017).…”

Shock tube data processing tools using open source hardware and software platforms

“…Also, the applications extend to the material processing, [12][13][14][15][16] manufacturing and other industries. 4,[17][18][19] Therefore, to get more applications out of shockwave phenomenon; it is very much required to produce shock waves in the laboratory or industry in a controlled manner. The instrument used to produce shockwaves in laboratory in a controlled manner is known as a shock tube or a shock tunnel.…”

Characterization of a novel open-ended shock tube facility based on detonation transmission tubing

“…Since the magnitude of these flow features depends on the initial pressure ratio between the driver and driven sections as well as the specific heat ratio of gas medium, shock tubes can be used to study aerodynamic flows in a wide range of temperatures and pressures, which are difficult to obtain in other types of testing facilities [4][5][6][7][8][9][10][11][12][13][14][15][16]. Additionally, shock tubes are applicable to fundamental research in medicine, biology, and industries [17][18][19][20][21][22][23].…”
