Optimization on the jet characteristics of the main nozzle of hot-blowing snow removal device [PDF]
Journal of Vibroengineering, 2022 The exhaust devices used by snow removal vehicles are mainly based on hot-blowing snow removal. Due to the inherent characteristics of the turbojet engine such as low flow rate and high exhaust temperature, the modified hot-blowing snow removal device has problems of low snow removal efficiency and the possibility of ablation and damage to the road ...

Design of a submarine main ballast blowing systems
Analele Universităţii "Dunărea de Jos" din Galaţi Fascicula XI Construcţii navale/ Annals of "Dunărea de Jos" of Galati Fascicle XI Shipbuilding, 2023 A submarine ballast system represents a combination of dedicated equipment and piping in which the main circulating fluid is either sea water straight from the submarine exterior or air which is compressed at high pressures and then it is stored in pressure vessels onboard.

Zhongguo Jianchuan Yanjiu, 2022 ObjectiveIn order to study the blowing and drainage performance of a submarine main ballast tank system, the simulation and experiment of main ballast blowing based on the short circuit blowing model are carried out. MethodsFirst, the short circuit blowing model is modified to simulate the process of air release and water drainage. Next, an equal scale

Dynamic Modeling of the Main Blow in Basic Oxygen Steelmaking Using Measured Step Responses [PDF]
Metallurgical and Materials Transactions B, 2008 In the control and optimization of basic oxygen steelmaking, it is important to have an understanding of the influence of control variables on the process. However, important process variables such as the composition of the steel and slag cannot be measured continuously. The decarburization rate and the accumulation rate of oxygen, which can be derived

Beam size blow-up and current loss in the Fermilab main ring during storage [PDF]
, 1977 Observations at Fermilab during the storage mode of operation show characteristic forms of transverse beam size growth and current loss with time. There are three obvious mechanisms which can produce such blowup. The gas pressure is a source for immediate beam loss by direct nuclear scattering. Protons can also multiple Coulomb scatter off the orbiting
