Estimation is to predict the outcome of seismic load to underground pipeline with manholes. Forces and shears were taken into account during modelling of seismic resistance. There were 3 types of waves identified in this job, and the estimation of the maximum velocity of the soil movement was made according to the category of soil by seismic properties. The seismic resistance was estimated under the action of both horizontal and vertical directions of seismic load. The model of a manhole was created from scratch by authors. The main supporting elements of the body were modelled in a stress-deformed mode. The transmission of seismic longitudinal P-waves was simulated with parameters up to 9 points inclusive at the MSK-64 scale in soils of medium density. Based on the analysis of the data obtained, a graph of maximum equivalent von Mises stresses was built depending on the phase of the seismic longitudinal P-wave transmission. Conclusions were made about the efficient usage of applying the proposed approach to solve this class of problems.
Вихревые трубы применяются в процессах подготовки и переработки природного газа, попутного нефтяного газа, а также при производстве метилового спирта и ацетилена. Выбор оптимальных конструкций и геометрических параметров вихревых труб осуществляется с помощью проведения физических экспериментов. Наряду с физическими экспериментами выбор оптимальных геометрических параметров может осуществляться при помощи математического моделирования в современных пакетах вычислительной гидродинамики (англ. computational fluid dynamics (CFD)), таких как ANSYS FLUENT. Математическое моделирование экономит
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
