The shape factor of the alumina nanoparticles significantly affects the flow recirculations and thermal exchange between the PCM and heat transfer fluid. Among various particles, cylindrical shaped one performs best while 23.8% reduction in charging time is obtained at the highest solid volume fraction...
(Re) on flow and heat transfer. Data for Nusselt number (Nu) and friction factor (f) are presented for air flowrates in the range 100 < Re < 1500. Performance evaluation and analysis of entry effects are made. The results confirm that the effects of both undulation height and Re are ...
Define Shape factor. Shape factor synonyms, Shape factor pronunciation, Shape factor translation, English dictionary definition of Shape factor. n. 1. The act of magnifying or the state of being magnified. 2. a. The process of enlarging the size of somet
Therefore, this work attempted to study the momentum and heat transport for MHD Jeffery-Hamel flow of hybrid nanofluids through converging/diverging surfaces. This analysis further evaluates the heat transport features subject to thermal radiation and nanoparticles shape factor impacts. A mathematical ...
Technical Note Experimental investigation of turbulent heat transfer and fluid flow in internally finned tubes Correlation of the data is difficult because of the many different parameters that can influence the Nusselt number and friction factor. The most widely ci... MK Jensen,A Vlakancic - 《Int...
Second, node classifications were entered as a four-level fixed factor in an MR-BPMM with B5 and B9 vitamin concentrations as response variables (Supplementary Table 10). B5 and B9 vitamin levels were compared across nodes that preceded the origin (1 versus 2), maintenance (1 versus 3) and...
In conclusion, with the help of this new method, optimal heating time for structural steel components, in the case of small cross-section and weight, can be determined. Keywords: structural steel; heating time; heat equalization; shape dependence; shape complexity factor; heat transfer...
Often cast components that are going to be placed under high loads will have included in the design parameter a “casting factor” that can be as large as a factor of 10 (Jolly, 1997). In other words, the designer is saying that he can rely on only one-tenth of the published ...
Further, the impact of the shape factor of scattered nanoparticles, such as Al2O3 and Cu, on the strength of energy transmission and the surface drag force is investigated and tabulated. It was found that the blade shaped nanoparticles possess higher Nusselt number (denoting rate of heat ...
Then, we learn an embedding space for a dataset with varying eccentricity and texture in Fig. 5a (nine classes). The UMAP and class distance matrix show that eccentricity is the dominant factor of variation over texture. Extending to the dataset with varying contour randomness (27 classes), ...
