Nowadays, the increasing demand for energy in the world is one of the main concerns for energy supply. In fact, the required energy can be obtained by increasing the production rate of fossil fuels such as oil and natural gas. However, improving the efficiency of the equipment and facilities might have a significant impact on production from hydrocarbon resources. With respect to this subject, ...

One of the problems in seed production pasture forage plants is low germination. Existing improvement technologies and technical means for production, harvesting, post-harvest handling, storage are analysed. Suggestions improving germination have been developed: it advisable to place crops between forest belts; improve germination, necessary make a preliminary harvest with spreading mass on stu...

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...

The Gaussian process model is an example of a flexible, probabilistic, nonparametric model with uncertainty predictions. It can be used for the modelling of complex nonlinear systems and recently it has also been used for a dynamic systems identification. Gaussian process models have become an emerging, complementary method for a nonlinear system identification. The output of the GP model is a ...

Pursuant to the high usage of rotating the disk in aircraft gas turbine engine, turbo pumps in oil and gas industries, steam and gas turbines in power plants, marine gas turbine and other industrial rotary machines designing and getting under the mechanical and thermal loading casued this design and analysis to be as a special significance. These disks are subjected to mechanical and thermal lo...

This paper presents a numerical study of the gas-powder flow in a typical Lapple cyclone. The gas flow is obtained by the use of the Reynolds stress model. The resulting pressure and flow fields are verified by comparison with the measured results and then used in the determination of powder flow that is simulated by the use of a Stochastic Lagrangian model. The separation efficiency and trajec...
