The novel coronavirus disease (COVID-19) spread pattern continues to show that geographical barriers alone cannot contain a virus. Asymptomatic carriers play critical role in the nature of this virus quickly escalating into global pandemic. may transmit unintentionally through sporadic sneezing. A Computational Fluid Dynamics (CFD) approach has been proposed with realistic modeling human sneeze achieved by combination state-of-the-art experimental and numerical methods. This be suitable for...
This study investigates the startup behavior of sodium heat pipes, focusing on how different methods, presence non-condensable gases (NCGs), and flow instabilities near mixing layer affect thermal performance operational stability. Four methods were evaluated, ranging from slow, incremental power increases to rapid, one-step applications. Thermal observed emerge at a critical 50.43 W, corresponding an operating temperature 340 °C. Slow startups initiated below this threshold enabled gradual...
Experimental data for the natural circulation of high-Prandtl number fluids in molten salt systems has not yet been sufficiently studied to ensure safe operation event a loss forced coolant. A loop facility was designed mitigate major challenges flow visualization experiments salt. Experiments were conducted with and water, four experimental sets obtained each working fluid at increased heater power. Particle image velocimetry (PIV) measurements performed, boundary layer analyzed as function...
In this study, an experimental investigation was conducted on the rising height and contact angle of fluid in annular wick-type heat pipe. The pipe characterized by a small gap between wick structure tube wall, which compensated for pressure drop along porous media created additional capillary force. To describe model advantage gap, wetting liquid vertical solid plate mesh (with them) experimentally measured analyzed. An experiment performed to investigate effect curvature rise using tubes...
Microreactor technologies are required to provide reliable carbon-free power generation in remote applications. The heat pipe–cooled microreactor concept, particular, offers notable advantages due the passive operation of pipes, enabling increased reliability and simplicity a more compact form factor. There is significant need for experimental work aid expedite deployment pipe microreactors their unique technological characteristics. Thus, there has been interest experiments by numerous...
Off-gas systems are implemented in molten salt reactor designs to control the release of gaseous fission products. Two-phase flow must be studied understand how system will behave comparison traditional working fluids like water. Flow visualization experiments and particle image velocimetry measurements were performed for three argon bubble sizes injected into a co-current stream natural circulation loop facility. Similar with water compare shape, trajectory, wake behavior fluids. The region...
The enhancement of latent heat thermal energy storage (LHTES) systems through fin geometry optimization remains a critical challenge for leveraging the full potential renewable sources. This study focuses on optimizing geometries tree-shaped fins to enhance power and densities in LHTES systems. goal is find branch designs with high density novel surrogate model-based strategy that explores broad design space. models applied, including linear regression, principal component analysis-based...
This study used an artificial neural network (ANN) regression model in wire-wrapped fuel assemblies to estimate the transition-to-turbulence flow regime boundary (RebT) and friction factor. The ANN models were trained validated using existing experimental datasets. bundle dataset comprised several design parameters, such as number of rods, rod diameter, wire lattice pitch, edge helical pitch. log–log scale Reynolds linearity characteristics coefficient over-sample factor laminar turbulent...
This study presents a new approach to flow regime classification specifically tailored for typical wire-wrapped fuel assemblies in sodium fast reactors. Historically, the definition and understanding of boundaries have been extensively researched. However, many these models suffer inaccuracy due lack comprehensive data. In particular, limited data, with only 36 data points laminar-to-transition boundary 145 transition-to-turbulent boundary, often result suboptimal models.
