Study the Natural Convection of Heat Transfer of Structural Steel Cylinder by Using Ansys Transient Thermal
Main Article Content
Abstract
Structural steel has become one of the most widespread building materials from last hundred year. It is broadly used in critical infrastructure such as buildings, cylinders, and marine pipelines, etc. In this paper, natural convection heat transfer is used for cooling steel cylinders by using ANSYS Transient Thermal. A cylinder is designed to have a radius of 10 mm and a depth of 40 mm. The initial temperature of the cylinder is 120°C and the ambient temperature is 22°C. When we apply a convection coefficient of 1x10-5W/mm2°C, the steel cylinder starts to cool down with the passage of time. The temperature decreases from 120°C to 22.357°C in the 10000s. These results show that the heat transfer (cooling rate) is rapid at the start of simulation but gradually decreases with the increase in time. When we apply the final convection coefficient of 2.2×10-5W/mm2°C, the temperature decreases from 120°C to 22.755°C in 3800s. These simulations show that the cooling rate has directly related to the Convection heat coefficient.
