An innovative and efficient design of solar receivers/reactors can enhance the production of clean fuels via concentrated solar energy. This study presents a new jet-type burner nozzle for gaseous feedstock injection into a cavity solar receiver inspired from the combustion technology. The nozzle design was adapted from a combustion burner and successfully implemented into a solar receiver and studied the influence of the nozzle design on the fluid mixing and temperature distribution inside the solar receiver using a 7 kW solar simulator and nitrogen as working fluid. Finally, a thorough computational fluid dynamics (CFD) analysis was performed and validated against the experimental results. The CFD results showed a variation of the gas flow pattern and gas mixing after the burner nozzle adaptation, which resulted an intense effect on the heat transfer inside the solar receiver.

The flow, bearing, and carrying capacity of the cycloidal hydrostatic oil cavity in hydrostatic turntable systems are numerically simulated, considering the rotation speeds of a turntable from 0 to 5 m/s and different boundary conditions. The vortex effect is weakened, and the stability of the oil cavity is enhanced with the increase in lubricant viscosity. However, the increase in inlet speed, depth, and inlet radius of the oil cavity causes the vortex effect to increase and the stability of oil cavity to reduce. With the increase in the oil film thickness, the carrying capacity of the oil cavity diminishes. The oil cavity pressure increases along the direction of the motion of the turntable; it is distributed unevenly because of the rotation of the turntable. With the increase in turntable speed, the location and size of the vortex scope in the oil cavity flow field and the strength of the vortex near the entrance gradually weaken and move away from the entry. The distribution of pressure is determined by the locations of the vortex. When the vortex is close to the wall, the wall pressure increases at its location. Otherwise, the wall pressure decreases first and then increases after the center of the vortex.
关键词: hydrostatic oil cavity flow state oil cavity pressure stability vortex

高压富水充填溶腔具有水量大、水压高、规模范围大、充填介质复杂的特征,工程施工风险极高,采用传统的注浆法进行处理,受地层的不均一性、材料选择、技术水平的影响,难免会出现注浆盲区,施工中一旦注浆盲区被高压水击穿,将会发生大规模突水突泥,造成灾害。针对宜万铁路所遇到的高压富水充填溶腔,通过科技攻关,提出采取释能降压新技术进行处治。经现场实践,安全、经济、可靠,并取得了成功。释能降压技术是针对高压富水充填溶腔采取有计划、有目的的精确爆破揭示,从而释放溶腔所存储的能量,降低施工及运营过程中水土压力对隧道形成影响,之后,通过配套处治措施完成溶腔治理。
