This paper presents a new method to calculate flow pressure for tight oil well with partial penetration fracture. The solution to the diffusivity equation can be obtained using dimensionless transformation, Laplace transformation, Fourier cosine transformation and other mathematical methods. The calculation ...
Furthermore, a complete mathematical model for fluid flow and pressure drop calculation is given in this paper as follow: Since the K values are functions of the stream Reynolds numbers, experimental data from 14 models have been correlated to give resulting equations for resistance coefficient K ...
Bottom-hole flowing pressure and pump intake pressure (PIP) are important parameters to optimize the performance of oil wells. In recent years, downhole sensors are becoming widely used in electrical submersible pump systems to measure these pressures. However, it is still rare to use downhole ...
All three methods couple calculation of the elastic deformation of the piston-cylinder with calculation of the pressure distribution in the piston-cylinder clearance from a flow model. After reviewing the calculation methods, the paper presents results for each of the comparison systems. The calculated...
MFCs provide a precise measure of gas flow through a tube that is unaffected by variations in temperature and pressure by measuring themassflow rate of gases rather than the volume flow rate.1 The flow rate is typically determined by thermal techniques that measure the temperature variation as th...
For Re=50, the drag force, the streamline pattern, and the pressure field around a moving sphere in a large periodic domain showed good agreement with data from literature on a single sphere in an infinitely large flow field. 展开 关键词: intermittent cascades log-periodic corrections turbulence...
I want to calculate SPL from it not in fluent. Can anyone tell me what is the procedure in Tecplot or excel? One thing I want to know that .ard file contains acoustic pressure. are these values P for 20log(p/p0)? and How to calculate OSPL after it? I will be highly thankful to...
Hi. I'm trying to determine the flow rates of water in a pipe network. At a junction in a pipe, for example a simple y junction where the water heads out of...
may i refer to my posting of 12 nov : one issue is k-ep for recirculating flows. validity of using k-ep for any recirculation even in the bulk (there may be parallel flow at walls) is a question mark. what happens when a submerged jet impinges on a wall ? k-ep ? pressure grad ...
In the Neumann-Kelvin formulation of flow around a ship hull with a free surface, one can calculate the wave resistance using two different methods: Havelock's formula, which is an estimate of the resistance obtained from the radiated waves in the far field; and integration of the pressure ov...
