Abstract Natural gas is a key energy source to achieve the carbon peaking and neutrality goals in China. Dehydration de-hydrocarbon process crucial for pipeline transportation of natural since water hydrocarbons would condense cause corrosion freeze-blockage pipeline. The supersonic separator innovative low-temperature separation equipment characterized by simpler structure higher refrigeration...

We introduce an effective method to actively induce droplet generation using negative pressure. Droplets can be generated on demand using a series of periodic negative pressure pulses. Fluidic network models were developed using the analogy to electric networks to relate the pressure conditions for different flow regimes. Experimental results show that the droplet volume is correlated to the pr...

In this study, mixed convection heat transfer and local and global entropy generation in aventilated square cavity have been investigated numerically. The natural convection effect isachieved by a constant heat flux imposed at the bottom wall and cooled by injecting a coldfollow. In order to investigate the effect of port location, four different placementconfigurations of the inlet and outlet ...

The tubeless vortex reducer was used to reduce the pressure drop in a cavity with radial inflow. In previous studies, mechanism of breakdown reducers not clear, and there lack direct guidance for engineering design. this paper, we studied detail by large-eddy simulation (LES) experiments. A mathematical model, which has high applicability compatibility, established guide pre-design reducers. LE...

Efficiency data for MVG trays with truncated downcomers are presented for the first time. Various operating conditions including vacuum and high pressure are considered. While 7 bar and 11 bar data are very promising it has been possible to show that a uniform liquid flow pattern does indeed affect the efficiency at atmospheric pressure positively. A special downcomer outlet device has been dev...

The aim of our study was to construct a bladder outlet obstruction nomogram for women with lower urinary tract symptoms. A urodynamic database of 600 consecutive women was reviewed. Bladder outlet obstruction, utilizing strict diagnostic criteria, was diagnosed in 50 (8.3%) patients. A comparison of patient characteristics, uroflowmetry, and detrusor pressure-uroflow studies was carried out bet...

Modeling of thermal-hydraulic calculations for the AP1000 core to predict reactor pressure vessel (RPV) temperature has been carried out. The reactor’s primary coolant system transfers heat produced in fuel during operation steam generator. Part will also be transferred from and pipe. This paper presents calculation result RPV prediction normal operation. Calculations were performed using COBRA...
