Thermodynamic Analysis of Variable - Diameter Pipes under Temperature
Journal Title: Scholars Journal of Engineering and Technology - Year 2017, Vol 5, Issue 5
Abstract
In the event of thermal expansion and contraction of the pipeline will produce thermal stress, due to the existence of thermal stress to reduce the diameter of the pipeline extrusion caused by deformation of the pipeline. In this paper, the finite element software ANSYS is used for modeling and analysis, and the eight-node solid element model is used to simulate the variable pipe. In this paper, we study the weak position of the variable pipe under the action of temperature, the influence of the temperature on the variable pipe, the influence of the temperature difference on the variable pipe, and the stress analysis of the variable pipe under the fire. The results show that the weak position of the variable pipe is located around the change of the pipeline under the action of temperature. The limit stress of the variable pipe is related to the temperature and temperature of the pipeline. The study provides a reference for the design of thermal pipelines, making the heat transfer variable diameter pipeline design reasonable energy saving. Keywords: variable pipe; finite element software; Temperature, maximum strain position; thermosetting coupling
