In high power laser systems, precision micro-machining is an effective method to mitigate the laser-induced surface damage growth on potassium dihydrogen phosphate (KDP) crystal. Repaired surfaces with smooth spherical and Gaussian contours can alleviate light field modulation caused by site. To obtain optimal repairing structure parameters, finite element (FEM) models for simulating intensification mitigation pits rear KDP were established. The intensity of these profiles was compared...
Due to the merits of energy saving and environmental protection, absorption chiller (AC) has attracted a lot attention, previous studies only concentrated on dynamic response AC under single working condition. However, conditions are usually variable, performance different is beneficial for adjustment control whole system, which stabilization can be affected by transient process. Therefore, steady models single-effect H2O-LiBr built up, thermal inertia fluid storage also taken into...

Supercritical carbon dioxide (S-CO2) powers cycles can achieve higher efficiency in a compact footprint and are suitable for various heat sources have great application potential number of energy industry. The printed circuit exchanger (PCHE) plays significant roles the due to its high thermal-hydraulic performance structure rigidity. In present study, sinusoidal channeled PCHE is investigated numerically compared with that conventional straight PCHE. effects structural parameters channels...
Marine water-lubricated rubber bearing is used to support the stern shaft of surface vessels and underwater vehicles, whose friction vibration noise directly influence stealth, security both physical psychological health occupants. In order investigate this problem, kinds bearings with different material were tested on testing machine, coefficient, noise, frequency amplitude measured under working conditions. The results show that coefficient are affected material, operating speed, applied...
Abstract The agglomerating fluidization behavior of different binary mixtures SiO 2 /TiO , /ZnO and TiO nanoparticles in vibro-fluidized bed (VFB) was performed. results showed that the existed obviously channeling crack formation at lower gas velocities slowly disappeared with increasing superficial velocity, then reached homogeneous state minimum velocity under certain amplitude (3 mm) frequency (40 Hz) vibrations applied. mean agglomerate size sampled top 224 μm, 187 μm 148 μm,...
Conical bearing is one kind of radial-thrust hybrid bearing, which can carry radial and axial load at the same time. A hydrodynamic lubricated conical sliding was designed computational methods were used to analyze lubrication carrying performance. The methodology employed fluid dynamics (CFD), based on Navier-Stokes equation a fluid-structure interaction (FSI) technique. Simulation results show that semi-conical angle, taper angle tapered land flat ratio are three important parameters...
Due to its high thermodynamic efficiency and small equipment size, the S-CO2 Brayton power cycle is a leading candidate for ship waste heat utilization. The hybrid exchanger formed by diffusion bonding of fins etched plates can be used exchange between temperature flue gas pressure S-CO2. However, law structural strength not clear exchanger. It critical carry out stress analysis. In this study, assess exchanger, FEM was compared with currently method from ASME codes. results show that...
