Pishenina N. Improvement of the method of determining the intensity of heat exchange in energy-efficient systems for recycling organic waste

A possibility of reducing the anthropogenic impact on the recycling by systems for organic waste (RSOW), substitution of natural gas to biogas, producing high quality fertilizer. Improved mathematical model RSOW, for example, of a biogas plant, con-cepts like technogenic load and reduction of anthropogenic impact on the environment were put into quality criteria. The experimental calculated method (ECM) assessment of the intensity of heat transfer in rheologically unstable mixtures has been proposed and experimentally and theoretically substantiated. The experimental base ECM and mathematical model for determining the heat transfer in the basic experimental installation has been improved taking into account the behavior of non-Newtonian fluids in various thermal and hy-draulic conditions. The experimental study of the heat transfer of non-Newtonian mixture has been made in a container with the dimensions on the edge of "large volume" - "limited volume" in the conditions of thermal instabil-ity. The method of determining the heat exchange under natural conditions in RSOW has been proposed, researched and recommended for the case when the thermophysical properties of the mixture are unknown and changing depending on its past history. The researches have been done of specific heat and technological systems of pro-duction energy carriers from organic waste.
