Analysis of transient heat conduction in pyinkado (xylia xylocarpa) using finite element solutions

This paper describes the one-dimensional, transient heat conduction in a rectangular piece of Pyinkado (Xylia xylocarpa) with cross grain and in an orthotropic wooden cylinder. Computerized solutions of a generalized, nonlinear heat equation are derived by discretizing the time domain using finite element techniques. | Analysis of transient heat conduction in pyinkado (xylia xylocarpa) using finite element solutions AGU International Journal of Sciences – 2019, Vol 7 (4), 91 – 99 ANALYSIS OF TRANSIENT HEAT CONDUCTION IN PYINKADO (Xylia xylocarpa) USING FINITE-ELEMENT SOLUTIONS Bui Thi Thien Kim1, Hoang Thi Thanh Huong1, Ho Xuan Cac2 1 Nong Lam University 2 Associate Technology And Science Sylvicultre Information: ABSTRACT Received: 10/09/2018 This paper describes the one-dimensional, transient heat conduction in a Accepted: 11/02/2019 rectangular piece of Pyinkado (Xylia xylocarpa) with cross grain and in an Published: 11/2019 orthotropic wooden cylinder.

A simplified example of linear heat conduction distribution of temperature on in cylindrical coordinates illustrates how to apply the finite element wood. solutions. The accuracy of the solutions for this special case is evaluated via comparing them with a well-known exact solution. The results could give significant information for fire-resistant solutions in house architecture and design. 1. INTRODUCTION The knowledge of transient temperature profiles In order to analyze an engineering system, a plays an important role in some wood uses, for mathematical model is developed to describe the instance, for simulating heat conditioning of logs behavior of the system. The mathematical in veneer and plywood mills and temperature expression usually consists of differential response of lumber in dry kilns. Since wood is a equations and given conditions. These hygroscopic and porous medium, heat transfer differential equations are usually very difficult to may occur by means of several modes: solve if handled analytically. The alternative conduction, convection and radiation. However, way to solve the .
