MATHEMATICAL INVESTIGATION ON THE EFFECT OF NUMBER OF BRANCHES ON WATER HAMMER
(Pushpa Publishing House, 2013-10-01)
This paper looks at water hammer with an emphasis on the number of branches. The mathematics of water hammer are described in a transient condition. This includes the momentum and continuity equations for conduits. A ...
Modelling Stratified Flow in an Inclined Flow Channel with a Bend
(International Scientific Press, 2013-07-01)
Multi-phase flows modelling in wellbore has always been a problem to the petroleum and many other industries. In the petroleum industry, correlations are presently in use, most of which are obsolete as their application ...
On the Solution of Confined Aquifer Flow Equations: Finite Difference Approximations
(Hikari Ltd, 2013)
In general, groundwater flow in porous media on a microscopic level is three-dimensional. However, when considering regional flow problems ie groundwater flow on a macroscopic level, it is noted that because of the low ...
Weak Solution of the Singular Cauchy Problem of Euler-Poisson-Darboux Equation for n= 4
(2013)
We consider the singular Cauchy problem of Euler-Poisson-Darboux equation (EPD) of the form utt+ k t ut=∇ 2u u (x, 0)= f (x), ut (x, 0)= 0 where∇ 2 is the Laplacian operator in R n, n will refer to dimension and k a real ...
Solutions of second-order partial differential equations in two independent variables using method of characteristics
(nternational Journal of Engineering and Mathematical Sciences, 2013-06-01)
In this paper we have classified second order linear PDEs into three types, hyperbolic, parabolic and elliptic. Hyperbolic equations have two distinct families of (real) characteristic curves, parabolic equations have a ...
Elementary partial differential equations
(Lambert, 2013-06-01)
The importance of partial differential equations cannot be gainsaid. They are used in science and engineering. Many natural phenomena such as sound, heat, electrostatics, electrodynamics, fluid flow etc occurring in science ...
Effects of Conduction and Variable Properties On a Two Dimensional Conjugate Heat Transfer of a Nanofluid in a Microchannel
(International Scientific Press, 2013-10-01)
In this paper we analyze the effects of conduction and variable properties on a two dimensional conjugate heat transfer of a nanofluid containing a mixture of two fluids namely, Aluminium oxide (Al2O3) and water. Nanoparticles ...
Supporting Information for: Rheological Properties of Blends of Isotactic Polystyrene–
(2013)
Figure S1: Optical micrographs and atomic force microscopy (AFM) images for the 95% iPpMS–5% iPS binary system dewetted at 𝑇dew= 240℃ and at different incubation times.(a) shows a 200 nm film before the dewetting ...
Exact analytical solutions for fully quantized parametric oscillation dynamics
(Routledge, 2013)
In this paper, a simple method for obtaining general analytical solutions of the time evolution equations for a fully quantized parametric oscillation process is developed. Heisenberg’s equations for the signal–idler photon ...
