In designing the heat exchanger model, the existing epsilon-number of transfer units (NTU) method cannot
reflect factors inside the heat exchanger, such as the local flow rate changes. Furthermore, it is difficult to apply a
three-dimensional model to a one-dimensional analysi...
The purpose of this study is to improve the simultaneous reduction of NOX and CO, harmful gases emitted from
internal combustion engines, at low temperatures using a Pt/TiO2 H2-SCR catalyst. A better NOX/CO reduction performance
was observed upon loading 2 wt% of the additive ...
Thermal management plays a crucial role for the energy efficiency of electrified vehicles. Using numerical flow

measure rolling resistance at +25 °C ambient temp...
Modern cars protect drivers and passengers in frontal, rear and offset crashes by using crumple zones to absorb
crash energy. This means that the car absorbs the impact of the crash, not the driver or passengers. Crumple zones allow the
front of the vehicle to crush like an ac...
