“…Modeling of thermo-hydraulic effects generated by ultrasound is of prime importance for the integration of this technology to optimize many industrial processes using heat exchangers. Some mathematical [38] and numerical [39][40][41] models dealing with hydrodynamic effects of ultrasound have been released. These models have been designed for low [39][40][41] and high [38] frequency range and specific conditions of use of ultrasound.…”

“…Some mathematical [38] and numerical [39][40][41] models dealing with hydrodynamic effects of ultrasound have been released. These models have been designed for low [39][40][41] and high [38] frequency range and specific conditions of use of ultrasound. It is therefore necessary to investigate, identify and qualify parameters involved on thermo-hydraulic effects induced by ultrasound in a larger way in order to feed these models.…”

The aim of this work is to quantitatively demonstrate the intensification of heat transfer in forced convection by mean of ultrasonic irradiation at low (25 kHz) or high (2 MHz) frequency. High frequency ultrasound induces convective acoustic streaming while low frequency ultrasonic waves produce mainly cavitation effects. These hydrodynamic phenomena are at the origin of strongly different observations in terms of flow pattern modification and thereby in Nusselt number values. A link is tentatively established between hydrodynamic behaviors at both ultrasonic frequencies and corresponding thermal results.Hydrodynamic approach was performed with a 2D-2C PIV device while thermal one was carried out under uniform heat flux conditions. It seems that thermal enhancement effect of acoustic streaming (2 MHz) decreases as flow rate increases. This behavior is consistent with the decrease of turbulent kinetic energy produced by acoustic streaming in the same

“…Within the same heating time, the temperature of the battery achieved by the proposed strategy is at least 7.6 ℃ higher than that of a constant amplitude pulse. A study conducted by Tablei et al [51]showed that the use of ultrasonic vibrations increases heat transfer efficiency by 175%, and increasing the oscillation amplitude leads to enhanced heat transfer. The above studies show that mechanical vibration could enhance heat transfer.…”

“…Results show that the oscillating relative velocity was a crucial factor for heat transfer augmentation by 11.43%. Talebi et al [80] investigated numerically the impact of upper surface oscillation on natural convection heat transfer in a cylindrical enclosure filled with air is by the FDM. They showed that augmentation of HTC can be up to 175% by inducing ultrasonic waves.…”

a b s t r a c tComputational fluid dynamic (CFD) is a simulation tool which utilizes the applied and computational mathematics for fluid flow regimes modeling to predict the heat, mass and momentum transfer behavior. In recent years, the solution's accuracy of the CFD simulations became within the acceptable range demonstrating that CFD is a valid tool for performance analysis and design development for many thermal-hydraulic systems. This encourages researchers to use it in the modeling of evaporation and condensation phenomena or two-phase flow with a vapor-liquid phase change process and mass and heat transports through the interface simulation which is one of the urgent difficulties in the solar stills development and analysis. The aim of this is to introduce a comprehensive review work of the highlights that have been made through the recent years for most important studies about the CFD approach as a tool for performance prediction and analysis in addition to design improvement and development for solar stills. This study is supported with a compact synopsis in the form of, computational domain (two or three dimensional), CFD software utilized, operating and geometrical parameter range, simplified assumptions and the better CFD results.
