Technical science and innovation
Convective drying refers to one of the energy-intensive processes used in chemical, woodworking, food and other industries. Therefore, in modern conditions, when there is a growing shortage and an increase in energy tariffs, it is important to develop and apply new effective methods of drying wet materials in industrial production, create high-performance drying equipment, improve the operation of existing dryers, which will contribute to the rational use of natural resources, reduce the cost of finished products and increase the competitiveness of production. Root crops are plants in which nutrients are concentrated in tubers or roots. Jerusalem artichoke refers to sugar-containing …

The problem of creating a compact refrigeration zone for absorbers with tubular-lattice nozzles made of pipes with spiral turbulators is discussed. Research has been carried out on the influence of the groove depth h/D and α/αгл of the step of their placement t/D on the degree of heat transfer intensification α/αо in the transition region of the gas-liquid flow. An intensification of heat transfer has been achieved only by increasing the groove depth from h/D = 0,003 to 0,095 and the optimal pitch of the grooves, the intensity of heat transfer is 2 or more times. Research has …

The paper presents the results of an experimental study of the intensification of heat transfer of a swirling flow in a cylindrical channel with two tangential and axial swirlers. During the experiments, such parameters were measured as: air flow in front of the vortex apparatus; hot water consumption; pressure drop in the vortex apparatus; temperature of working media at the inlet to the apparatus and at the outlet of it. A method for intensifying the heat transfer process, which is based on swirling a gas stream by its tangential supply, has been developed and investigated. Experimental studies of the intensity …
