Evaluation of hydrodynamic flows of cellular fluid in artificially formed continuums of plant material structure

Abstract

Aim. The aim of the research is to evaluate hydrodynamic flows of cellular fluid in artificially formed channels of the structure of plant materials as a result of exposure to atmospheric spark discharge. The article presents some features of the flow of cellular fluid in artificially formed channels of plant materials after passing an atmospheric spark discharge. Expressions of hydrodynamics of idealized physical models are used to describe them. As a confirmation of the received data, the experimental part has been set.The Methods. The authors consider the case when the initial plant material is pre-treated with a spark discharge; its influence arises a new continuum in the structure of the material in the form of a throughinduced channel. Expressions of intracellular fluid outflow time and pressure power based on Poiseuille's law are given for electrically induced channels. The experimental part of the work includes spark discharge treatment of plant material – carrots cut into discs with a diameter of 24 mm and a thickness of 3 and 9 mm to determine the dependence of the amount of released cellular fluid on the duration of the experiment and the discharge current mode.The Results. It has been established that atmospheric spark discharge treatment contributes to the formation of new continuums in the structure of plant materials. With an increase in the intensity of treatment, the area of the moisture trace from the carrot disk increases and, as a result, the amount of released intracellular fluid. For the sake of clarity of the experiments, graphs of the dependence of the processing intensity on the amount of liquid released have been presented, corresponding expressions given.Conclusion. The obtained experimental data and dependencies will be useful when considering more complex mass transfer processes in capillary-porous bodies using preliminary electrophysical processing.
