We developed steamer discharge plasma working on N2, CO2, and Air feed gas. We also developed reaction chemistry for CO2, N2, and Air plasma to understand the production of short-lived species. Our 0D and 1D models are ready nowadays; we are focused on developing 2D models. 2D models in two different phases took a very long time to standardize due to complications in fluid flow in two distinct phases. Our 2D model is very close to the experimental conditions of the gas and liquid phase. OD and 1D model COMSOL model were helpful in predicting the very short reactive species those were are not possible to detect through the physical parameters. like We also measured the reactive species in the gas and liquid phase. Further, we measured the changes in the reactive species using a chemical analysis Kit and Fluorescence spectroscopy for the liquid phase analysis, and FT-IR used for the gas phase analysis. We analyzed our plasma system on the radish seeds to find out the change in germination index and growth. Also new analyzed the production of the NO3- species inside the seeds. We also checked the production of reactive production in the gas phase like CO, and O3 using FTIR. And detected the NH4+, NO3-, NO2- and H2O2 concentrations in the water using chemical analysis. Later, we also checked the production of OH radical in the water using the Fluorescence spectroscopy. The detection of OH, N2 second positive system, NO, CO, Alpha-H were detected in the gas phase using Optical emission spectroscopy. Our Simulation results are in the good agreement with the experimental results

我们开发了在N2，CO2和空气馈电气体上工作的蒸笼排放血浆。 我们还为CO2，N2和空气等离子体开发了反应化学，以了解短寿命物种的产生。如今，我们的0D和1D型号已准备就绪；我们专注于开发2D模型。由于流体流动的并发症在两个不同的阶段中，因此2D模型在两个不同的阶段中进行了很长的时间来标准化。我们的2D模型非常接近气相和液相的实验条件。 OD和1D模型COMSOL模型有助于预测通过物理参数检测到的非常短的反应性物种。就像我们还测量了气相和液相中的反应性物种。此外，我们使用化学分析试剂盒和荧光光谱进行了液相分析，并测量了反应性物种的变化，以及用于气相分析的FT-IR。我们在萝卜种子上分析了血浆系统，以找出发芽指数和生长的变化。还分析了种子内NO3种的生产。我们还使用FTIR检查了气相中的反应性产量的产生，O3。并使用化学分析检测到水中的NH4+，NO3-，NO2-和H2O2浓度。后来，我们还使用荧光光谱检查了水在水中的产生。使用光发射光谱检测在气相中检测到OH，N2第二个阳性系统，NO，CO，Alpha-H。我们的仿真结果与实验结果非常吻合
