In this study, a combined drying technique is numerically studied to amplify the electro-hydrodynamics (EHD) drying rate of porous bodies through a smooth channel. The finite volume approach was applied to conduct a code to solve the governing equations. To highlight more details of some guessed key parameters such as the gap size between the obstacles (bricks) and the positions of the emitters, the analysis is extended to find out the most efficient arrangement of the combined technique for higher drying rates with lower electrical power consumptions. As an overall criterion, the specific energy consumption (SEC) was introduced; the energy consumption for evaporation per unit mass of the moisture. The computed results revealed that the guess was correct and gap size joint with the positions of the emitter has remarkable effects on the EHD drying rate and consequently the SEC. It was found that the applied various arrangements caused an average change of SEC between 707 kJ/kg to 13350 kJ/kg. This is while the maximums of SEC for the cases with further emitters from the grounded plate is about 17 times greater than those obtained from other sets.

EHD执行机构通过光滑通道在多障碍物作用下利用多种障碍物干燥多孔体的组合技术

在这项研究中，对组合干燥技术进行了数值研究，以放大通过光滑通道的多孔体的电-水动力学（EHD）干燥速率。应用有限体积方法进行代码求解控制方程。为了突出显示一些猜想的关键参数的更多细节，例如障碍物（砖块）之间的间隙大小以及发射器的位置，扩展了分析范围，以找出结合技术的最有效布置，以更高的干燥速率和更低的电功率消费。作为总体标准，引入了单位能耗（SEC）。每单位质量的水分蒸发所消耗的能量。计算结果表明，这种猜测是正确的，并且间隙尺寸与发射器的位置有关，对EHD干燥速率和SEC有显着影响。发现所应用的各种布置导致SEC的平均变化在707kJ / kg至13350kJ / kg之间。与此相对，如果接地板有更多的发射器，则SEC的最大值大约是从其他装置获得的SEC的最大值的17倍。
