Effectiveness of solar heating systems for the regeneration of adsorbents in recessed fruit and vegetable storages

The dependence of the amount of energy obtained by solar cells on the temperature of the environment

“…In the passport characteristics of the solar cells used in practice, the index values suitable for the Mediterranean climatic conditions are given. [8][9][10][11][12][13][14]. The standard conditions are the ambient temperature of 25 ℃ and solar radiation of 1000 W/m².…”

Simulation of hydrodynamics of the dispersed layer of fruit during solar-convective drying

“…There are many equations for calculating the pressure drop in random packages of spherical and lumpy (irregularly shaped) granular bodies [2][3][4][5][6][7][8][9][10][11]. In foreign and domestic practice, the Ergan equation (internal problem) is most often used at 0.1<Re<10 4 according to equation ( 2 At low Reynolds numbers (laminar mode Re<2*103), equation ( 4) turns into equation (5).…”

“…When considering the hydrodynamics of a stationary layer, two main models are used [2][3], in which a layer of particles is considered as:  A system of winding channels with a characteristic hydraulic diameter (internal task filtration model).  A set of particles flown around a moving flow (external problem -flow model).…”

Mathematical modeling of greenhouse-livestock complex heated by solar and bioenergy sources

“…On sunny days, the solar energy that enters the greenhouse is stored underground and in a water tank located between the livestock building and the greenhouse. On chronic cloudy days, a microclimate is created in the greenhouse at the expense of gas from the biogas plant [9][10][11][12][13]. The mathematical model of the combined thermal greenhouselivestock complex with the design of the thermal regime of constructive, technical, technological, and meteorological systems can be written as follows:…”
