Formulation of the Finite Difference for 1-D Heat Transfer. This equation involves the second derivative of temperature with respect to a spatial dimension (i.e., x) and the first derivative of temperature with respect to time; Let's take a closer look at how these derivatives are formed for a numerical solution. 46
Numerical methods and techniques are intro-duced for estimation of performance deterioration such as flow non-uniformity, temperature non-uniformity and longitudinal heat conduction effects using FEM for CHE unit level and Colburn j factor and Fanning friction f factor data generation meth-ods for various types of CHE fins using CFD at fin level.

Finite-element analysis of cyclic heat transfer in a shell-and …
1997年6月1日 · To answer these questions, a finite-element model is developed to simulate the cyclic thermal process occurring in a shell-and-tube latent heat thermal storage exchanger. This exchanger consists of a tube which is surrounded by an external coaxial cylinder made up of a phase-change material (PCM).
2016年8月10日 · Chapter 1 contains the general description of the boundary value problems of interest and has been expanded with a section on mathematical preliminaries and a section on low-speed compressible ßows. 2 continues with the introduction of the Þnite element method and is essentially unchanged.
Finite element modeling of borehole heat exchanger systems
2011年8月1日 · Single borehole heat exchanger (BHE) and arrays of BHE are modeled by using the finite element method. The first part of the paper derives the fundamental equations for BHE systems and their finite element representations, where the thermal exchange between the borehole components is modeled via thermal transfer relations.
