Application of a Volterra quadratic polynomial to modeling elements of heat engineering devices

Antipina E., Spiryaev V., Tairov E. Application of a Volterra quadratic polynomial to modeling elements of heat engineering devices // E3S Web of Conferences. Vol.114. ID: 01007. 2019. DOI: 10.1051/e3sconf/201911401007 This paper considers integral models built to describe dynamic processes in a 135 MW power unit condenser. For this purpose, we use a quadratic segment of the Volterra integral power series. The first set of models was built with a perturbation of the cooling water flow, and the second...

Experimental determination of the induction period for the onset of intensive boiling of a subcooled water flow under conditions of unsteady heat release

Safarov A., Levin A. Experimental determination of the induction period for the onset of intensive boiling of a subcooled water flow under conditions of unsteady heat release // E3S Web of Conferences. Vol.114. ID: 07004. 2019. DOI: 10.1051/e3sconf/201911407004 This paper studies prediction of the boiling crisis onset under conditions of the rapid temperature growth of the heat releasing surface washed by a water flow subcooled to the saturation temperature. We obtained experimental data on time...
