Temperature distributions in end closures of annular fuel elements
Nuclear Structural Engineering, 1965Abstract The temperature distributions in bonded end closures of annular fuel elements, such as those often used in nuclear superheating power reactors, are determined analytically. The solution for the temperature distributions is represented by products of the Bessel functions with hyperbolic functions.

Radiation and creep analysis of strains and stresses in annular fuel elements☆
Nuclear Engineering and Design, 1965Abstract A theoretical analysis for the determination of strains and stresses produced in long, annular reactor fuel elements is presented. In the analysis, primary effects of thermal-cycling growth, irradiation growth, swelling, creep and neutron flux levels developed in the fuel material are taken into account. An exact solution based on a product

Influence of the Fuel Distribution in Double Annular Combustors on the Emissions
Russian Engineering Research, 2021The double annular combustor of a low-emission combustion chamber in a gas-turbine engine based on natural gas is considered. The distribution of fuel supply in the double annular combustor is investigated, and its influence on the toxic emissions is determined.

Optimum configuration of an annular nuclear fuel element
Nuclear Engineering and Design, 1970Abstract In all-ceramic fuel elements for high temperature gas-cooled reactors, an unfueled moderator spine is often surrounded by a fuel compact consisting of a dispersion of fuel and fertile material in a moderator matrix with a ceramic cladding. For given fuel and fertile loading in a fuel element of given outer size, physical reasoning suggests ...

Thermomechanical Performance of High-Power-Density Annular Fuel
Nuclear Technology, 2007To have adequate confidence in the proposed design of the internally and externally (I&E) cooled annular fuel, it is important to identify the fuel operational constraints from a materials performa...

Investigating an annular nozzle on combustion products of hydrocarbon fuels
Thermophysics and Aeromechanics, 2013Full-scale and computational experiments were used to investigate the flows in the jet thrust unit with annular nozzle and deflector in the form of a spherical segment. The used working gas was the combustion products of air mixtures with acetylene, gas-phase aviation kerosene, and natural gas.
