The Numerical Calculation of the Behavior of the Gas Bubble, Fixed on the Solid Surface
Abstract: The existing literature data permit only qualitatively to trace the behavior of gas bubble, fixed on the solid surface, with the narrow range of Bond numbers (β). For investigation of the profiles, common surface energy of gas bubbles and equilibrium of forces, which retain bubbles on the solid surface in the fluid, the computer model of numerical calculation of the profile, surface square, volume of the gas bubble, fixed on …

Effect of Fusion Plasmas in Complete and Incomplete Fusion
Abstract: Abstract In an attempt to study the effect of thermal fusion plasma in complete and incomplete fusion, the collisional cross sections of several medium and/or heavy were measured with increasing plasma density, temperature and pressure and analysed with TALYS-1.4 code. The measured plasma density, temperature and pressure profiles are analysed with numerical model transport code PTRANSP, ONETWO and ASTRA and the corresponding data were used for calculations. The excitation functions …

Study on the Rocking Phenomenon of Parachute Rope
Abstract: With the constant development of computer technology and the development of numerical simulation techniques, the simulation of the dynamics of the parachute is becoming increasingly accurate. To eliminate the effects of large deformation of the grid in the conventional parachute simulation, we chose the parachute model using the smooth particle hydrodynamics method and performed a steady-state fluid-solid coupling numerical simulation, which is in good agreement with the calculated gas power …

Study on the Method of Constructing a System of Linear Equations for Calculating Aerodynamic Derivatives
Abstract: The aerodynamic derivatives can be calculated from the unsteady hydrodynamic forces experienced by the harmonic-oscillating vehicle. Until now, unsteady flow field analysis in aerodynamic derivative calculations has been applied mainly to thin bodies based on potential theory MSC. Nastran is a typical application based on potential theory MSC. Natran can calculate the aerodynamic derivatives of the vehicle relatively well in the subsonic region, but in the supersonic region, the fuselage …

Simulation of Threshold Voltage Variation of Enhancement Mode n-channel MOSFET
Abstract: AbstractThe paper focuses on simulation of variation of threshold voltage as a function of effective channel length of the short-channel MOSFETs with a Gaussian-like doping profile. An investigation of short channel effect (SCE) in deep submicron region has been carried out. The validity of the proposed simulation is shown by comparing the results with the numerical calculation and simulation of data obtained by using the commercially available simulation software. Finally, …

Review of Subsea Pipeline for Minimizing Thermal and Pressure Expansion
Abstract: As the offshore oil and gas fields have been exploited in deeper water, subsea pipelines are required to operate at high temperatures and pressures. It causes subsea pipelines to be more subject to movements both in lateral and axial directions due to the loads produced by high temperatures and pressures. Some high temperature pipelines have experienced the cumulative axial displacement of an overall pipeline length over a number of start-up/shut-in …

Enhancement of Power Quality in a DG-Integrated Smart Grid Using UPQC
Abstract: The goal of this presentation would be to demonstrate how an upqc conditioner may be used to improve the strength of a dispersed energy (DG) system (UPQC). Despite the potential advantages of DG, which include increased energy supply, reduced power system growth, and environmental friendliness, there are numerous problems assimilating DG into the system or sustaining it in standby mode. Voltage profile (PQ) is a significant technological barrier in dispersed …

Study on the Profile and Flow Field Variation of Parachute Coating by Seven-hole Probe Method
Abstract: In general, the parachute test is a long test cycle, expensive, and difficult to measure with accuracy, which makes it a very laborious and time-consuming task. Therefore, attempts have been made to overcome this by using a parachute test stand or by simulation, but in our country, there is no numerical simulation of the parachute and there is no research on it. In this paper, the variation of the shape …
