the technique used to control the airflow is based on the electro-hydrodynamic actuator which is also called plasma actuator. this actuator ensures the airflow control thanks to the electric wind created by the electrical corona discharge. this ionic wind is developed at the profile surface tangential to the initial free airflow so that it has a significant effect on the boundary layer flow. th...

ABSTRACT Foliar fertilization is a highly efficient technique of applying needed plant nutrients. During pulverization in the field, incompatibility between fertilizer and pesticides can cause clogging spray nozzles. So, this work aims to improve solubility foliar fertilizers facilitate its application. The effect airflow, inlet gas temperature, feed solution flow rate over yield, productivity,...

the natural ventilation is an easy way to exchange the indoor polluted warm air with outdoor fresh air. the wind power injects outdoor fresh air into the building. a good indoor air current and subsequently a proper exhaust depend on the openings’ conditions and their situations. a serious architectural question is under what conditions of the openings the wind-cross ventilation can be effectiv...

Ventilation airflow in buildings is paramount important for creating comfortable environment with acceptable indoor air quality by regulating indoor air parameters, such as air temperature, relative humidity, air speed, and concentrations of chemical species in the air. Airflow inside naturally ventilated dairy (NVD) building is highly variable because of the direct effect of outside weather an...

Correct inhalation technique is essential for effective use of dry powder inhalers (DPIs), as their effectiveness largely depends on the patient's inhalation manoeuvre. Children are an especially challenging target population for DPI development due to the large variability in understanding and inspiratory capacities. We previously performed a study in which we determined the prerequisites for ...

An imaging-based computational framework for simulation of airflow in subject specific breathing human lungs is established. The three-dimensional (3D) airways of up to 9 generations and lobes are segmented and reconstructed from computed tomography (CT) images. Beyond the CT-resolved 3D airways, a volume filling method is applied to generate the one-dimensional (1D) conducting airway tree that...

An airflow window has great potential for conserving energy and improving indoor air quality in residential buildings. Existing airflow windows use a single airflow path, and their energy performance can be studied using several computational models. A dual-airflow window with triple glazing can conserve more energy than a singleairflow window, because the former works like a cross-counterflow ...

BACKGROUND Over the past few decades, evidence has emerged suggesting that nasal airflow asymmetry and brain asymmetry are linked. The nose exhibits asymmetrical airflow, with the dominant airflow alternating from one nasal passage to the other over a period of hours. Some authors have suggested a correlation between cerebral hemisphere dominance and nostril dominance. Others have proposed an a...

An appropriate estimate of a building airflow network, which consists of infiltration and interzonal airflow, is important when determining indoor air quality, energy use, and for detecting contaminants. The objective of this study was to estimate the airflow network of a commercial building using CO2 as a tracer. CO2 is naturally present in the environment and is generated inside buildings by ...

In electric vehicles, the battery pack is one of the most important components that strongly influence the system performance. The battery thermal management system (BTMS) is critical to remove the heat generated by the battery pack, which guarantees the appropriate working temperature for the battery pack. Air cooling is one of the most commonly-used solutions among various battery thermal man...
