Staff from the Commercial Fishery Department carried out experiments at the hydraulic channel of Fishering Service

Staff from the Commercial Fishery Department conducted a series of experimental studies at the Fishering Service hydraulic channel. The experiments were carried out as part of a Russian Science Foundation (RSF) research grant on the topic of Physical, Mathematical and Computer Modelling of Netting Engineering Structures, Considering External Impact Factors.

Candidates of Engineering Sciences A.O. Razhev, P.V. Nasenkov, and K.V. Konovalova participated in the research under the supervision of the Department Head, Candidate of Engineering Sciences A.A. Nedostup. They are developing a mathematical and simulation model to assess the influence of mesh orientation in relation to fluid flow in axisymmetric netting engineering structures under conditions of hydraulic thrust and external influences on shape and loads, using a codend containing a catch as an example.

Over the course of several weeks, experimental studies were carried out on models of codends made of polyethylene. They were mounted on frames of various diameters to achieve different degrees of opening with varying hanging ratios. The codend models also had different mesh widths and T0 and T90 netting orientation.

The Commercial Fishery Department at KSTU would like to thank the Director of Fishering Service, A.N. Fedorov, and, in person, the Director of the flume tank, M.A. Nazarkin, for providing the opportunity to carry out a large series of experimental studies in the hydraulic channel.
