Project "Creation of design of experiments and metamodeling methods for optimization of dynamics of multibody 3D systems interacting with bulk solids and fluids"

It is planned to use the developed optimization methodology and methods for designing bulk material loading equipment that would prevent the generation of harmful and explosive dust that is very actual problem, for example, in Riga port terminal (See, B.Kļava. Black as the devils. In  Weekly magazine Ir:  August 15, 2018.). Therefore the results of this fundamental research will also provide methods for engineers to reduce environmental pollution. It is also planned to carry out optimization of patented original autonomous vehicle that would be capable to use for underwater inspections and reconnaissance for military needs due to its very low acoustical emission level. A working prototype has already been developed in RTU by project members. The project is in line with two priorities in science (#Climate change, nature protection and environment; #State and public safety and defence) which have been determined by the 13 December 2017 LR Cabinet of Ministers Decree No. 746 "On Priority Directions in Science for 2018-2021".

  AUV.      Dust suppression hopper.

 The work results will significantly contribute to the interdisciplinary field of science Computational mechanics which encompasses mechanical engineering, numerical mathematics, and computer science. The principle of double-helicoidal trust creation for AUV (patented by project members) aroused great interest at several international conferences of maritime mechanics (see Left Fig.).

Dust suppression during transportation of bulk materials (such as potash and grain) is extremely important for environment protection. The modelling results showed that vibrations (self-excited or forced) can separate the hopper outflow so that the larger particles form the external flow shell while the finer dust remains inside the flow (see Right Fig). The cooperation will be aimed on potential commercial application for bulk cargo transportation equipment manufacturer as DSH Systems Ltd. located in New Zealand.
