The nozzle spray range is an important parameter in the design of sprinkler systems because it affects the wetted area and water application rate. In this study, the jet deformation parameter k jet , which can measure the mass and shape of the jet microelement, was investigated, and a spray range prediction model for a rotating nozzle was established based on the modified ballistic trajectory equation. A comparison verified th...

The multifractal structure of shale pores significantly affects the occurrence of fluids and the permeability of shale reservoirs. However, there are few studies on the multifractal characteristics of shale pores that distinguish between organic and inorganic pores. In this study, we obtained the pore size distribution (PSD) of organic and inorganic shale pores separately by using a new NMR-based method and conducted a multifr...

Assessment of the natural frequency of the offshore wind turbine (OWT) system is a critical task in design to avoid resonance. The natural frequency of the monopile supported OWT may change during operation and needs to be calculated regularly. Conventional numerical methods separately model different components of the OWT system using various element types, which require tedious data manipulations and are inefficient to asses...
