A thick tip foil blade was designed to reduce the tip leakage flow and weaken the tip vortexes in ducted propeller 19A/Ka4-55. The thick tip foil was constructed by normal extrusion of the original tip foil. The maximum thickness of the foil increased from 1.64% chord length to 7.64%. The commercial...

Gas mask in the process of wearing, in the role of breathing air flow, so that the uneven distribution of pressure inside the cover body, resulting in deformation of the cover body structure, so that the protective performance of the gas mask failure. In this paper, this paper takes the gas mask as an...

The numerical simulation of the hydrostatic bearing of the fluctuating load is carried out by Ansys cfx. The variation law of the oil film thickness with the load is obtained and compared with the static formula. It reveals the influence of periodic variation of the load displacement interface table....

The T106 axial turbine series is used extensively by major engine manufacturers, because of its ability to give the best performance at low pressure conditions. However, it has high secondary flow development. The present work aims at understanding the effect of high gas velocities and high temperatures...

In order to improve the micro-high-speed centrifugal pump cavitation performance, to understand its internal cavitation characteristics. The internal flow field of the centrifugal pump model established by UG was simulated by CFX software. The performance of the centrifugal pump in different speed, flow...

Submarine Pipeline is used widely in ocean engineering now. In order to study the mass ratio’s effect on the submarine pipelines’ vortex-induced vibration, two-degrees-of-freedom vortex-induced vibrations of the pipelines with large and small mass ratio are simulated with the software ANSYS-CFX. When...

In this study, three turbulence models k-
, standard k-  and SST Gamma Theta which all available in ANSYS CFX were used. Gamma Theta Model is the recommended transition model for general-purpose applications. The full transition model is based on two transport equations, one for the intermittency and...

Torque Converter Clutch (TCC) works longer than ever before because of slipping technology intervention. The friction coefficient of TCC friction plate will change with temperature. In order to get the dynamic friction coefficient and also ensure the friction plate temperature not too high, TCC temperature...

In the present work, computational simulations were made using SST turbulence model with Gamma Theta model which available in ANSYS CFX. Multi-trench configuration consists of two trenches together, one wider trench and the other is narrow trench that extruded from the wider one. Multi trench configuration...

An analytical algorithm for solving the nonlinear bending deformation of a thin-walled hollow bridge pier under the action of water flow considering the fluid-structure coupling effect, is proposed. Initially, The kinematic equation and the dynamic equation on the wetted surface of the structure are...

the sewage networks functioning is accompanied by the processes of intensive emission of sewage gases (hydrogen sulfide, methane, ammonia, carbon dioxide) from the sewage stream into the air. Subsequent gas distribution due to the entraining stream ability results in gas accumulation in the under-roof...

ANSYS CFX software is used to simulate and analyze the axial -fan for heat sending in the pipe tunnel kiln, and find the relationship between the total pressure and the total pressure efficiency of the fan at different blade angles and different inlet air flow conditions. According to analyze the effects...

Korea experienced a recession in the shipbuilding industry due to a decline in orders for vessels and a lack of orders from the Korean market. In 2017, the amount of orders has increased compared to the previous year, but it is expected to be only 60% of the previous level in 2020. However, it will be...

In this article a bell mouth junction assembled in front of the test article in practice was simulated by applying ANSYS CFX, the data of relative measurement points was picked up from the simulation result and compared with test data to validate the simulation reliability. Then, aiming to dwindle in...

Sudden water pollution accidents have great harm to the ecological environment of human society. In recent years, the water pollution accident has been the main content of the environmental pollution accident in our country. It is very necessary to simulate and evaluate the impact of sudden water pollution...

In this study, a turboexpander for geothermal energy ORC power system was desgned. R245fa was selected as the working fuild. The factors which influence the performance of the trubine were analyzed and discussed. The software Ansys-CFX is used to perform preliminary steady-state CFD simulations. The...

There is enormous evidence that the initiation and growth of atherosclerosis is highly influenced by hemodynamic factors. In this study, hemodynamic factors in the following patient specific 3D carotid artery models were studied: i) normal, ii) stenosis (with plaque near to bifurcation of internal carotid...

The abundant of solar in tropical countries is an advantage of utilizing solar energy. One of them is the use of the stack effect through the solar chimney. Experts have widely discussed the use of solar chimney in buildings. It concluded that solar chimney in buildings was able to increase the air velocity...

In the survey stage of nuclear power plant site, it is necessary to consider the impact on nuclear power station brought by the aircraft. The most serious consequence is the fuel leak. The fuel combustion process is divided into two stages of deflagration and pool fire. This paper is mainly focus on...
