Method for experimental data processing in the sphere of hydrodynamics of packed heat and mass exchange apparatuses

Abstract

The article dwells on the method for summarizing experimental data on hydrodynamics of one-phase filtration flows through packed heat-and-mass exchange apparatuses differing in configuration. Summarizing is performed using a modified generalized equation. The described method simplifies the work with experimental bulk data, helps to compare the packed heat-and-mass exchange apparatuses, assess their energy performance and find the ways for their industrial implementation in heat-and mass exchange equipment.

Modelling and calculation of a small-size evaporation cooling apparatus for industrial recirculated water with a heat-and-mass exchange packing based on wastes from metal-working machinery

“…The analysis of the provided experimental data (ref. to Table 1) and comparison with the performance of the packing contact devices that are widely used in the industry [58][59] make it evident that the studied packing material ensures a high permeability of the packing block (Low values of specific flow resistance) and even organization of the liquid flow mode through the layer of the packing materials with different density of irrigation and besides ensures a relatively high liquid retaining capacity [51,52,54]. A rather high efficiency of the studied material with regard to heat-and-mass exchange performance has been experimentally proved (ref.…”

The use of industrial wastes from machine-building enterprises as packing materials for small-sized absorbers for gas emissions purification

“…The results of experimental studies of packing devices in hydrodynamics of a singlephase filtration flow through the packing layer are shown in Figure 2 (filtration curve 1). Its further processing with the classification criterion dependence λ=f(Rem) described in detail in [44,45] allows predicting the effective industrial use of any packing materials samples. The developed classification technique λ=f(Rem) is especially relevant in the conditions of processing and comparison of large amounts of experimental data and in particular in multiple studies of waste samples from machine-building enterprises (metal shavings).…”

The determination of hydraulic resistance during laminar filtration through layers of sorbents and ion-exchange granules in environmental mass exchange equipment

“…Filtration flows are used in many industrial processes and products of various branches of mechanical engineering, in technologies and equipment of the chemical industry and related industries [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17]. Filtration is used in water treatment processes and in environmental technologies .…”
