| 9th International Conference on Fluid Flow, Heat and Mass Transfer (FFHMT’22) | Niagara Falls, Canada | 2022 | 08/06/2022 - 10/06/2022 | International ASET Inc | Intensification of Heat Transfer by the Method of Artificial Roughness at a Water Film Flows down on Vertical Pipe | oral | The article presents the results of an experimental study to determine the effect of two-dimensional, pyramidal and combined roughness on heat transfer when a water film flows down the outer surface of a vertical pipe. A two-dimensional roughness was created by winding a wire around a pipe. The pyramidal roughness was created by cutting the left and right screws on the pipe, as a result of which the pipe surface was covered with densely spaced truncated pyramids of height - k. The combined roughness was created by a combination of the above two types with different heights - h and relative step - s/h of two-dimensional roughness. Three regimes of manifestation of the effect of roughness on the intensity of heat transfer were identified: 1. Regime without manifestation of the effect, 2. Regime with partial manifestation of the effect and 3. Regime of full manifestation of the effect of roughness on heat transfer. It was experimentally established that the maximum increase in the heat transfer intensity (more than 3.5-times) is achieved in the case of using a combined roughness with geometric parameters: k=0.25mm, h =0.7mm, s/h =10. It was also found that the effect of the combined roughness (pyramidal + spiral) on heat transfer in the entire range of the Reynolds number investigated by us is higher than the effect of both two-dimensional and pyramidal roughness. | https://institutes.gtu.ge/uploads/FFHMT_160 Edited.pdf |

A.V.Lykov National Academy of Sciences of Belarus | Intensification of heat transfer when a water film flows down a vertical pipe | oral | It has been experimentally established that the creation of two-dimensional roughness on the heat-transfer surface causes a significant increase in the intensity of heat transfer into a film flowing down the surface of a vertical pipe. The highest effect is achieved with the ratio of the step between the roughness elements to their height s/h=10. | http://mif16.itmo.by/doc/Full_program_.pdf |
