本研究藉由三維數值模擬一截面為1 mm × 1 mm、長為100 mm、由中心點火往兩端開口傳遞之方槽內反應波與震波生成及傳遞動態，槽內初始為298K靜止之C2H4+3O2，分別針對槽內初始壓力、二氧化碳稀釋與壁面鋸齒三種參數，探討震波與反應波間之交互作用對於緩燃焰加速與轉爆震焰加速過程之影響。
槽內初始壓力會影響燃氣質量燃燒率與分子間碰撞機率，於0.05 MPa下會熄焰且無法向前傳遞；0.1 MPa結果顯示，前導震波的生成不僅預壓縮更預熱了火焰面前方未燃氣體，且完全發展之後的正向回饋效應會使爆震焰產生；0.2 MPa時，由於壓力增加導致質燃燒率與分子間碰撞機率大幅增加，使得反應波尖端速度快速提升，於50 s便成功轉變為爆震焰，DDT所需時間與距離大幅縮短了150 s 與32 mm。等溫壁面373 K、二氧化碳稀釋=0.1條件下，前導震波發展階段中反應波尖端壓力會逐漸消散，使得阻滯效應影響大幅降低，因此無法成功產生爆震焰並熄焰。絕熱壁面、二氧化碳稀釋=0與=0.1兩組案例中，二氧化碳稀釋會使得化學反應速率變慢，導致DDT所需時間與距離增加了59 s與12.3 mm。
壁面鋸齒案例中，於一點火後便迅速引燃，並產生前導震波於反應波前方，震波接觸鋸齒之後反射至中心會進一步累積反應波壓力使DDT產生；由反應波速度圖可以得知，壁面加入鋸齒壁面鋸齒能使原本無法產生DDT之直槽成功由緩燃焰轉變為爆震焰。

Three dimensional numerical simulation was used to model the formation and propagation of shock waves and reaction waves propagated from the middle end toward to open end in a millimeter-size channel, which was 1 mm depth and 100 mm length. Initial conditions for channel were C2H4+3O2 at 298 K. The effects of interaction between two waves on deflagration acceleration and deflagration-to-detonation transition (DDT) were observed for different initial channel pressure, CO2 dilution and zigzag cases.
The initial pressure would affect mixture burning rate and probability of molecular collision. As a result, reaction wave could not propagated and quenched in 0.05 MPa case. In 0.1 MPa case, the results showed that the shock wave not only pre-compression but also pre-heat the unburned gas in front of reaction wave. Detonation occurred due to positive feedback effect flame accelerated and DDT transition occurred. In 0.2 MPa, burning rate and probability of molecular collision increased due to large pressure. Velocity of reaction wave increased suddenly and DDT occurred at 50 s. In constant wall temperature 373 K and CO2 dilution =0.1 case, the reaction wave pressure dissipated continuously at leading shock formation stage. The effects of choking decreased results in flame quenching. In adiabatic wall and CO2 dilution =0.1、=0 cases, CO2 dilution would slow the chemical reaction.
In zigzag cases, the flame propagated just after ignited and leading shock formed. Shock wave reflected to the channel centre would accumulate pressure of reaction front and make DDT occur. From figure of reaction wave speed, Sidewall zigzag did make DDT occur in channel that couldn't have DDT at all.
