RESULTS OF NUMERICAL SIMULATION OF A REGENERATIVE SELF-ROTATING AIR HEATER

A methodology for calculating aerodynamic torques and friction torque in the support units of a regenerative rotary air preheater is presented. Results of numerical modeling are shown, reflecting the dependence of the total torque on the guide vane angle and the boiler heat load. Based on the calculations, operating co...

Simulation of Condensation Flow and Heat Transfer in Spiral Tube Heat Exchangers for Non-Azeotropic Hydrocarbon Mixtures.

As a core component of the natural gas liquefaction process, spiral wound heat exchangers play a crucial role in LNG production. To comprehensively understand the condensation flow and heat transfer characteristics of non-azeotropic hydrocarbon mixtures inside spiral tubes. The high-precision numerical investigation in...

Computational fluid dynamics investigation of heat transfer, pressure loss, and exergy efficiency in serpentine solar air heaters with variable turn numbers

Solar air heaters have been widely used for space and industrial process heating. However, serpentine Solar Air Heaters (SAHs) exhibit limited thermohydraulic efficiency due to high pressure losses caused by the bends. To address this, the present study numerically investigated different configurations of serpentine...

Numerical Investigation of Coolant-dependent Heat Transfer Performance in Jacketed Reactors

The thermal performance of jacketed reactors is strongly influenced by the thermophysical properties of the applied heat transfer fluid. While analytical methods provide rapid engineering estimates, they are often unable to describe local flow structures and temperature distributions within the jacket space. In the pre...

An overview of heat pipe models in Sockeye

Abstract The heat pipe code Sockeye, led by Idaho National Laboratory and funded by the Nuclear Energy Advanced Modeling and Simulation program of the U.S. Department of Energy, provides engineering-scale models of high-temperature heat pipes for use in nuclear microreactors. Sockeye has three heat pipe models, referre...
