“…As an alternative method to the above mentioned method, ANN is used as a general correlating tool which belongs to artificial intelligence methods, and used in different fields [ [22] , [23] , [24] , [25] , [26] ]. A new ANN is proposed here with an aim to establish the correlation between the significant parameters obtained from Spearman’s method to find a regression fit to the data and defining the correlation coefficient ( r ).…”

Background and aims Meteorological parameters play a major role in the transmission of infectious diseases such as COVID-19. In this study, we aim to analyze the correlation between meteorological parameters and COVID-19 pandemic in the financial capital of India, Mumbai. Methods In this research, we collected data from April 27 till July 25, 2020 (90 days). A Spearman rank correlation test along with two-tailed p test and an Artificial Neural Network (ANN) technique have been used to predict the associations of COVID-19 with meteorological parameters. Results A significant correlation of COVID-19 was found with temperature (T min ), dew point (DP max ), relative humidity (RH max , RH avg , RH min ) and surface pressure (P max , P avg , P min ). The parameters which showed significant correlation were then taken for the modeling and prediction of COVID-19 infections using Artificial Neural Network technique. Conclusions It was found that the relative humidity and pressure parameters had the most influencing effect out of all other significant parameters (obtained from Spearman’s method) on the active number of COVID-19 cases. The finding in this study might be useful for the public, local authorities, and the Ministry of Health, Govt. of India to combat COVID-19.

“…They found that a vertical inlet and outlet, right triangle, and high depth‐to‐width ratio benefit the uniformity of the velocity distribution. Naphon et al 7 analyzed nanofluids jet‐impingement heat transfer and pressure drop in the microchannel heat sink by an artificial neural network; the results aligned well with the experimental results. Son et al 8 numerically studied the oxidative coupling of methane (OCM) and the steam reforming of methane (SRM) in a microchannel reactor.…”

Bionic fractal microchannel plates are becoming popular because of their low pressure drop and high heat‐transfer efficiency. But there is still no systematic research on the heat and mass transfer mechanism of bionic fractal microchannel plates, which has limited their widespread use. A mathematical model of heat and mass transfer in bionic fractal microchannel plates is developed and the influences of their structural parameters on heat and mass transfer are evaluated. The results provide a systematic knowledge of bionic fractal microchannel plates which may help to guide their optimization for practical applications.

“…Asadi et al 19 claimed that Al 2 O 3 ‐MWCNT/thermal oil hybrid nanofluids are beneficial to heightening the heat transfer efficiency. Furthermore, Coulomb force, 20,21 external magnetic source, 22 pulsating flow 23 and jet impingement 24 can also reinforce the efficiency of heat transfer. Javed et al 25 reviewed the heat transfer of nanofluids in diverse heat transfer devices like tubes in detail.…”

To solve the high heat dissipation of the heat sink, a set of experimental device for the flow and heat transfer of the nanofluids through a heat sink filled with metal foam was established in this paper. The impacts of metal foam with diverse pore densities (PPI = 20, 30, 40), nanoparticle mass fractions (from β = 0.0 wt% to β = 0.5 wt%) and Reynolds numbers (Re = 414-1119) on the flow and heat transfer characteristics were investigated. In addition, the thermal and hydraulic properties were evaluated by the exergy efficiency and entropy generation. The conclusions displayed that the metal foam with a pore density (PPI = 40) is instrumental in strengthening the heat transfer under a certain porosity, and the heat sink under the working condition (β = 0.3 wt% and PPI = 40) possesses the best capacity of thermal performance. Nanofluids and metal foam (PPI = 40) can improve Nusselt number by 6.13% and 3.2% at most compared with water and metal foam (PPI = 20 and PPI = 30), respectively. Nanofluids with β = 0.3 wt% exhibit the highest exergy efficiency, and the metal foam with PPI = 40 shows the smallest entropy generation.
