| Abstract: | The required effectives of EGR-coolers and two EGR-coolers were tested in order to determine their relative efficiencies. The influence of coolant flow characteristics and soot on EGR-coolers was also studied. Based on analysis of testing results and numerical results by Star-CD software, the improving design of the flex-fin cooler was put forward and it is proved to be high efficiency. |
