Cth hydrocode
WebThe shock and detonation properties of the explosive PBXN-103 have been simulated with the use of the CTH hydrocode. These simulations require an unreactive Hugoniot relationship; a reactive equation of state (EOS) and a reactive rate law. One reactive rate law of interest is the Lee-Tarver ignition and growth model. To obtain parameters for the … WebCTH is influenced greatly by its predecessor codes, CHARTD, a one-dimensional hydrocode written by Sam Thompson in 1972 and CSQ, also written by Sam in 1975. …

WebCTH hydrocode simulations require high resolution; on the order of 80 cells per millime-ter. We found considerable numerical oscillation around the material interface of explosive products and air at lower resolutions. This means 160,000 cells for a one-dimension(1-D), 2 meter domain in spherical coordinates. WebThis study examines the ability of the CTH hydrocode to predict the effects of rod nose shape on the threshold impact velocity, whereby tungsten alloy long rods transition from rigid-body to eroding-rod penetration during penetration or perforation of thick aluminum targets. Two rod nose shapes hemispherical and ogival were used in the simulations, …
WebIn this project an Eulerian-Lagrangian hydrocode was used to simulate the super compression detonation shock tube configuration with an inert core and a reactive multiphase core. WebHydrocode Modeling Details Both the one- and half-inch diameter Cylex tests were simulated using the CTH hydrocode [9]. The simulations were run in two-dimensional, radially-symmetric cylindrical coordinates, with a mesh size of 0.00787 inches and time increments short enough to resolve the shock ringing in the cylinder walls (<0.05 …
WebJan 1, 2015 · We employ the CTH hydrocode to evaluate baseline shock behavior. The regular, ordered mesh of CTH allows for a consistent and precise application of the artificial viscosity. Direct numerical comparisons are used rather than experimental data to eliminate uncertainty due to factors such as material characterizations, EOS models, and mesh ... WebDec 1, 2015 · A similar study was performed with CTH hydrocode to check the effect of spall strength . variation in CTH (Fig. 4b). Interestingly, CTH simulation with 1.32 GPa showed a dip in .
