Numerical Simulation and Parametric Study of Hartmann- Sprenger Tube Based Powered Device
Numerical simulations of unsteady flow in a Hartmann resonance tube are carried out with the goal of understanding the effect of jet Mach number on the flow characteristics. The device, which consists of a convergent nozzle facing a closed end tube produces a nearly normal shock that fluctuates in the gap between the nozzle and the tube. Numerical solutions were obtained for the unsteady Reynol...
متن کاملThermal Design Considerations and Performance Evaluation of Cryogenic Tube in Tube Heat Exchangers
Heat exchangers are the most important equipment in refrigeration processes. Design and modeling of heat exchangers operating at low temperatures are different from other regular heat exchangers. This study includes two sections. In the first section, design and modeling considerations needed for evaluating the real thermal behavior of heat exchangers at low temperatures were discussed. The...

متن کاملShack-Hartmann Thermal Lensing Characterization of Mid-IR Materials
High brightness mid-IR sources have matured and are becoming viable solutions to many medical, defense, and sensing demands. Recently, super-continuum from 3.6-4.8μm with an average power of 22W has been demonstrated using a ZGP optical parametric oscillator [1]. To fully utilize the power and bandwidth of sources like these, passive optical components possessing both high optical and high ther...
متن کاملEvaluating the effect of transmissive optic thermal lensing on laser beam quality with a shack-hartmann wave-front sensor.
We examine wave-front distortion caused by high-power lasers on transmissive optics using a Shack-Hartmann wave-front sensor. The coupling coefficient for a thermally aberrated Gaussian beam to the TEM(00) mode of a cavity was determined as a function of magnitude of the thermally induced aberration. One wave of thermally induced phase aberration between the Gaussian intensity peak and the 1/e(...
