Flowline with Resistive Electric Heating System
The article deals with electric heating systems applied in flowlines for providing their continued operation in wintertime. The problem of obtaining a given distribution of heat output along the length of the pipeline with electric heating system has been solved. It allows to maintain the same temperature sections being in different environments. As the object of investigation a polymer tube with an integrated electrical heating is chosen
The simulation model of sliding contact with three degrees of freedom and distributed parameters of the transition layer
The development of theoretical approaches to determining mechanical characteristics of sliding contacts by the creation of a simulation model of a sliding contact with three degrees of freedom and distributed parameters of the transition layer is considered. This model enables to obtain dynamic and integral characteristics of the sliding contact on design parameters given and characteristics of materials of contact pairs
