Analyzing the universality of the dimensionless vibrating number based on the effective moisture diffusivity and its impact on specific energy consumption

Experimental Study on Vibrating Fluidized Bed Solids Drying

“…Similar to Daleffe et al [35] and Meili et al [21,36], we also found that the drying behavior is not similar for the four cases we tested using a 𝛤 value equal to 0.5. Fig.…”

“…Various vibration amplitude-frequency combinations could lead to exactly the same dimensionless vibration acceleration 𝛤 . Daleffe et al [35] and Meili et al [21,36] explained that this ratio should be chosen with care. In this analysis, we first examine the bed hydrodynamic behavior of the dimensionless vibrational acceleration equal to 0.5.…”

“…Lehmann et al [18] pointed out that mechanical vibration enhances the drying kinetics due to the increase of available transfer surface or the increase in transfer coefficients. Perazzini et al [19], Stakić and Urošević [20] and Meili et al [21] also reported improved drying rates when mechanical vibration was applied. In order to obtain a better understanding of the interplay between the improved bed hydrodynamics and the solids drying by applying mechanical vibration, more detailed information is required on the local hydrodynamics and local bed temperature.…”

Influence of microwave vacuum drying on the effective moisture diffusivity of seedless white grapes

“…However, inappropriate drying methods can lead to nutrition loss and microbial proliferation, ultimately lowering the raisin quality (Olivati et al, 2019) Hence, emerging novel food processing methods have aroused the attention of researchers. The methods involve incorporating techniques such as pressure, ultrasound, vacuum, microwave (Peña-Gonzalez et al, 2019;Shabbir et al, 2019), freeze and microwave (Li et al, 2020), high humidity and hot air (Bai et al, 2013), pulsed electric field (Nowacka et al, 2019), vibrating fluid (Meili et al, 2020), convective and microwave (Izli & Polat, 2019), and radio frequency-vacuum (Zhou et al, 2018) into the drying process. These novel drying techniques are designed to achieve cost-effectiveness, operational simplicity, and energy efficiency.…”

Evolution of Temperature Field around Underground Power Cable for Static and Cyclic Heating

“…A few experimental studies have been conducted so far to model diffusioneffusion driven drying in cemented particulate matter [33]. The lack of knowledge is due to improper understanding of the couple effects, and also the unavailability of the coupled partial differential equations to define the problem considering diffusion-effusion coupled with the heat transfer in unsaturated porous media is a limitation in proper modelling with numerical methods [34].…”
