a new form of expression for the young-laplace equation is proposed. the young-laplace equation is developed in a convenient polar coordinate system and programmed in matlab?. the profile generated showed to be in agreement with those reported in literature. an algorithm that avoids profile ...
Laplace's equation is an example ofa partial differential equation, which implicates a number of independent variables. In the usual case, V would depend on x, y, and z, and the differential equation must be integrated to reveal the simultaneous dependence on these three variables. What is the...
We begin with Laplace’s equation: ? 2V = 0 (1) We can write the Laplacian in spherical coordinates as: ? 2V = ? 2V 1 ? 2 ?V 1 ? ?V 1 (r )+ 2 (sin θ )+ 2 ( 2) ?r ?θ r 2 ?r r sin θ ?θ r sin 2 θ ?φ (2) where θ is the polar angle measured ...

Enrico Scalas, in Physica A: Statistical Mechanics and its Applications, 2006 Using the Laplace–Fourier method and recalling the properties of Laplace–Fourier transforms of convolutions, one gets the following solution of the integral equation [37,58–60]: (16)p(x,t)=∑n=0∞P(n,t)λn...
