Fuel Cells for Transportation

2022-09-01
This is a three-day course which provides a comprehensive and up to date introduction to fuel cells for use in automotive engineering applications. It is intended for engineers and particularly engineering managers who want to jump‐start their understanding of this emerging technology and to enable them to engage in its development. Following a brief description of fuel cells and how they work, how they integrate and add value, and how hydrogen is produced, stored and distributed, the course will provide the status of the technology from fundamentals through to practical implementation.

Aluminium alloy material cylinder head is a popular choice for any air cooled internal combustion engine. But when it is exposed to higher temperature, it is vulnerable for its loss in strength. It becomes imperative to maintain cylinder head temperature well below acceptable temperature limit. Efficient cooling system play a vital role to achieve this objective. In the present work, an air-cooled diesel engine is converted into CNG engine configuration for 25kVA genset configuration. A 1D gas-exchange model is created to generate the thermal boundary conditions required for Computational Fluid Dynamics (CFD) analysis. A steady-state 3D Conjugate Heat Transfer (CHT) model, that uses the predicted in-cylinder temperatures as a spatially varying boundary condition, is created to predict the convective heat transfer between engine fins and cooling air. A cylinder liner mounted Fan is modelled using the Moving Reference Frame (MRF) approach.
