The phrase "airflow movement" is correct and usable in written English.
It can be used in contexts related to physics, engineering, or environmental science, particularly when discussing the dynamics of air in a given space.
Example: "The design of the ventilation system was optimized to enhance airflow movement throughout the building."
Alternatives: "airflow dynamics" or "air movement".
A well-established multi-zone (CONTAM) model, based on reliable boundary conditions from CFD simulations, is used to analyze the airflow movements and pollutant transport between flats via door and window leakage cracks under different scenarios.
Hence human movement can disturb the air distribution in a local region and influence the airflow motion in the airplane cabin.
Additional measures are typically recorded and may include oral and/or nasal airflow, abdominal movements, electrocardiogram, and pulse oximetry.
The polysomnography concerned electroencephalogram (EEG) derived from 9 channels (F3-T3, T5-O1, T4-T6, Fz-Cz, T3-Cz, T6-O2, Fz-Cz, T3-Cz, and Cz-T4), electrocardiogram (ECG), naso-oral airflow, chest movements, oxygen saturation, electrooculogram (EOG), and electromyogram (EMG) from the submandibular, thoracic, and anterior tibialis muscles.
Second, we could not adjust respiration-modulated autonomic activity, especially HF and LF, in our study because we were unable to measure key respiration parameters, such as nasal and mouth airflow, chest wall movement, and abdominal movement, by polysomnography during the daytime monitoring period.
All patients underwent a standard sleep study, using the minimal patient contact sleep diagnosis system (VISI-3, Stowood Scientific Instruments Ltd (SSI), Oxford), which included the following parameters: digital Video/audio, calibrated sound level measurement, electrocardiography, R-R timing, pulse transit time, airflow, respiratory effort, body position and movement.
Main Outcome Measures: Apnea index, determined by sleep study (including chest wall movement, airflow, oxygen saturation), and daytime sleepiness, determined by Epworth sleepiness score.
Dissatisfaction was mostly caused by a lack of airflow and air movement in the space as well as excessive direct sunlight from the windows.
Partial polysomnography (RM60 study: airflow, chest wall movement, oximetry, snoring, pulse) was subsequently arranged because of mild somnolence and snoring, which was highly suggestive of obstructive sleep apnoea.
Since the airflow from front to back of the cabin (longitudinal direction) is minimal [ 6, 7], the longitudinal movement of the aerosols of case 1 is mainly due to the initial momentum given by the cough.
