MODELING OF HYDRODYNAMICS AND HEAT TRANSFER IN CHANNELS OF STEAM GENERATING SYSTEMS OF SHIP NUCLEAR POWER INSTALLATIONS OF AN INTEGRAL TYPE

The work demonstrates the possibility of theoretical modeling of hydrodynamics and heat transfer processes in complex channels of steam generators of integral-type shipboard nuclear power plants. A diagram is given and the operating principle of a nuclear reactor and steam generator cassette is briefly outlined. A grid model of a prototype heat exchange channel with double-sided heating was built to perform thermal-hydraulic calculations in the ANSYS CFX software package, and the calculation scheme was verified by comparing the results obtained with experimental data.
