Optimal Pareto Parametric Analysis of Two Dimensional Steady-State Heat Conduction Problems by MLPG Method
Numerical solutions obtained by the Meshless Local Petrov-Galerkin (MLPG) method are presented for two dimensional steady-state heat conduction problems. The MLPG method is a truly meshless approach, and neither the nodal connectivity nor the background mesh is required for solving the initial-boundary-value problem. The penalty method is adopted to efficiently enforce the essential boundary co...
متن کاملHeat diffusion in inhomogeneous media Steady state conduction
The system under examination consists of a mix of N discrete particles embedded in an otherwise continuous matrix. We will assume that the particles are spheres. The spheres each have a radius Ri, thermal conductivity κi, and position ri = (xi, yi, zi) relative to a common origin, for i = 1, 2, . . . , N . Assume that the radii are dimensionless (scaled with an appropriate length, e.g., the ave...
متن کاملNon-steady-state heat conduction in composite walls.
The problem of heat conduction in one-dimensional piecewise homogeneous composite materials is examined by providing an explicit solution of the one-dimensional heat equation in each domain. The location of the interfaces is known, but neither temperature nor heat flux is prescribed there. Instead, the physical assumptions of their continuity at the interfaces are the only conditions imposed. T...
متن کاملSteady-State and Transient Loop Heat Pipe Modeling
The NASA-standard thermohydraulic analyzer, SINDA/ FLUINT (Ref 1), has been used to model various aspects of loop heat pipe* (LHP) operation for more than 12 years. Indeed, this code has many features that were specifically designed for just such specialized tasks, and is unique in this respect. Furthermore, SINDA is commonly used at the vehicle (integration) level, has a large user base both i...
متن کاملSteady-state conduction in self-similar billiards.
The self-similar Lorentz billiard channel is a spatially extended deterministic dynamical system which consists of an infinite one-dimensional sequence of cells whose sizes increase monotonically according to their indices. This special geometry induces a nonequilibrium stationary state with particles flowing steadily from the small to the large scales. The corresponding invariant measure has f...
