Plant–atmosphere heat exchange during wind machine operation for frost protection

Experimental evaluation of the wind convection heat transfer on the glass cover of the single‐slope solar still

“…In 1932, Rowley et al 13 developed a similar empirical expression involving convection and radiation. By excluding the radiation component, Watmuff et al performed wind-tunnel experimental studies and established the purely convective term relating the convective heat transfer coefficient and wind speed as displayed by Equation (2). Similar results are obtained by Sparrow and Tien 14 by performing wind tunnel experiments on a square plate for a wide range of inclinations.…”

“…The wind convection heat transfer coefficient is of great importance in several research fields, such as building energy analysis, 1 research on animal and plant biology, 2,3 environmental sciences, 4 and energy systems research 5–8 . Appropriate estimation of h w is essential for solar‐based systems.…”

Wind Machines for Frost Damage Mitigation: A Quantitative 3d Investigation Based on Observations

“…While the observed features like ''inversion erosion'' and ''plume drifting'' agree with the literature, we hope to provide more experimental evidence for various night conditions in future studies. In addition, more wind field measurements coupled with temperature data will help to understand the heat exchange between air and plant tissue (Boekee et al, 2023).…”

“…The warming effects at the plant-scale depend on the heat exchange between air and plants. A detailed discussion on air-plant heat exchange during wind machine operation can be found in a companion study (Boekee et al, 2023). Our study will use air temperature as the indicator for frost protection (Perry, 1998) and focus on the first two complexities.…”
