Abstract

Fins are extended surfaces used between two fluids for heat transfer between the hotter and colder fluid or between a solid and a fluid. There are various types of fins, viz. angular fins, circular fins, and rectangular fins. Engine piston chamber is the most precarious part of any automobile imperiled to extreme thermal shocks, hence prone to thermal stresses. Therefore, fins are introduced to cool the cylinder, which helps to improve engine performance considerably. In this study, rectangular and circular types of fins were selected, and its effect on temperature distribution and heat flux has been studied for with and without the introduction of slots. Firstly, different fins were modelled by using AUTODESK FUSION 360, then meshing and post-processing were done using ANSYS WORKBENCH. The results (plots of temperature and heat flux distribution) obtained for various case studies have been analyzed and compared which showcased that the slotted circular fin geometry having higher fin thickness (3 mm in this case) is the preferred fin geometry compared to other types of fin. Key words: Fins, Autodesk fusion 360, Ansys workbench 2020 academic Software, temperature distribution, and heat flux.

不同型号内燃机气缸翅片厚度变化及引入狭缝的瞬态热分析

翅片是两种流体之间的延伸表面，用于热流体和冷流体之间或固体和流体之间的传热。鳍片有多种类型，即角鳍、圆形鳍和矩形鳍。发动机活塞室是任何汽车中最不稳定的部分，容易受到极端热冲击，因此容易产生热应力。因此，引入了翅片来冷却气缸，这有助于大大提高发动机的性能。本文选取了矩形翅片和圆形翅片，研究了在引入和不引入槽的情况下，其对温度分布和热流密度的影响。首先利用AUTODESK FUSION 360软件对不同翅片进行建模，然后利用ANSYS WORKBENCH进行网格划分和后处理。对各种案例研究的结果(温度和热流密度分布图)进行了分析和比较，结果表明，与其他类型的翅片相比，具有更高翅片厚度(在这种情况下为3mm)的开槽圆形翅片几何形状是首选的翅片几何形状。关键词:翅片，Autodesk fusion 360, Ansys workbench 2020学术软件，温度分布和热流密度。
