在过去十年中，微波频率范围内的大气压放电因在材料加工、CO₂分解、废物管理、制氢、水处理等领域的应用前景而受到广泛关注。本研究开发并表征了一种基于波导的微波大气压等离子体射流（MW-APPJs），重点关注其设计、诊断方法和运行参数。该装置包含微波电源、包括施加器段在内的微波波导网络，以及用于测量等离子体特性的诊断工具。研究采用光学发射光谱（OES）分析活性物种，并确定等离子体参数，包括电子激发温度（Tₑₓc）和电子数密度（nₑ）。表征结果突出了空间和时间梯度、气体流速以及功率输入对等离子体行为的影响。通过光学发射光谱测得，电子激发温度和电子数密度随功率增加而变化，同时还绘制了热电偶读数随功率的变化曲线。
英文摘要
Over the past decade, atmospheric pressure discharges in the microwave frequency range have gained significant attention due to their promising applications in material processing, CO2 dissociation, waste management, hydrogen production, water treatment, and more. This study presents the development and characterization of a waveguide-based microwave atmospheric pressure plasma jet (MW-APPJs), focusing on its design, diagnostics, and operational parameters. The setup incorporates a microwave power source, microwave waveguide networks, including the applicator section, and diagnostic tools for measuring plasma properties. Optical emission spectroscopy (OES) is employed to analyze the reactive species and determine plasma parameters which include electron excitation temperature (Texc) and electron number density (ne). The characterization highlights the influence of spatial and temporal gradients, gas flow rates, and power input on plasma behaviour. From OES, the Texc and ne variations were against the power increment. The thermocouple variations are also plotted with power.
