Study on the Effects of CO2/O2 Backpressure Environment on Diesel Injection Characteristics
Four different droplet breakup models were used to numerically simulate the diesel fuel injec-tion process in a constant volume combustion bomb at room temperature.The results show that the spray morphology simulated by the KHRT model is the closest to the experimental results.The spray penetration distance decreases with the increase of the backpressure medium density,the spray cone angle increases with the increase of the backpressure medium density,and the spray penetration distance decreases with the increase of the percentage of CO2 in the CO2/O2 mixture,and the spray cone angle is just the opposite.
