Thermal Analysis of IPMSM with Water Cooling Jacket for Railway Vehicles

Numerical Analysis of Cooling Effects of a Cylinder Head Water Jacket

The aim of this study is to discover the characteristics of the cooling water in the cylinder head of a high-power diesel engine by using the Computational Fluid Dynamics (CFD). A 3-D geometric model of a cylinder head water jacket was previously constructed using Unigraphics software. A mesh was then imposed on the model using the preprocessor of Fluent software, GAMBIT. Three types of thermal...

Thermal advection analysis of cooling waves of Iran

Survey of advection of cold waves in Iran is the main aim of this study. In this regard, 45 synoptic stations were employed and studied. In order to investigate the thermal advection of cold waves, 1000, 850, 700 and 500 hp levels were reviewed and analyzed. Results indicated that cold waves in Iran most affected thermal advection caused by Tibet- Siberia, Siberias integrated Turkmenistan high-...

Effect of inlet flow condition on the thermal behavior of battery pack using a wavy cooling jacket

In recent years, the automotive industry has experienced a dramatic mutation in the develop ment of electric vehicles. One of the most important aspects of this type of vehicle is its thermal management. Among the various parts of an electric vehicle that are subjected to thermal management, the battery is of particular importance. Battery cell temperatures may exceed the allowable range due to...

Structural Crashworthiness of Railway Vehicles

As a form of transport, rail has always maintained lower accident levels than its counterparts, the car and the airplane. The railway industry, however strives for still better safety measures to be implemented – a fact which intensifies with each accident that occurs. In the last years the continuous developments in technology, computer modeling capabilities and know-how have opened up various...
