Local aerodynamic characteristics, such as velocity profiles of airflow at various cross sections of the respiratory tract, depend mainly on the structures of the airway segment under consideration and upstream airways. Understanding of the local aerodynamic characteristics derives mainly from experimental ...
UNDERSTANDING THE INS AND OUTS OF THE MOBILE AIR-CONDITIONING SYSTEM It’s a pretty powerful feeling isn’t it – adjusting the flow and temperature of the clean, filtered air being delivered to your cab. With the season underway it’s a service you rely on to stay comfortable and even sa...
What is the general flow of air through the lower respiratory system from the trachea to alveoli? What is the pathway by which high pCO2 affects ventilation? What are the diffusion paths of oxygen and carbon dioxide during external and internal respiration? What is the mechanism...
One way airflow The airflow through the lungs is unidirectional as opposed to the “in and out” tidal flow of mammals (Scheid & Piiper 1972) (Fig. 6.46). The parabronchi, being tubes and not dead-end sacs like alveoli, allow for continuous gas exchange in the avian lung and this ma...
or stored for later. A controlled atmosphere in ultra-low-oxygen storage (CA/ULO) increases the storage time while maintaining the product’s original taste. Compressors are an integral part of the pressure swing adsorption (PSA) process, which generates the nitrogen necessary to create the optima...
Additional factors which affect the deposition profile are physiological (inhalation rate, tidal volume, volumetric flow rate of inspired air of breathing, breathing pattern) and human anatomical parameters (ICRP 1994; Aleksandropoulou and Lazaridis 2013; Brown 2015). In the respiratory tract modelling...
There are numerous research studies focusing on airflow in the respiratory system that assumed flow to be only laminar and steady. The goal of this research is to describe the air flow mathematically by considering the resistance from both laminar and turbulent airflow throughout the entire ...
you get restricted airflow. If a building can't breathe, you get stagnant air. On top of that, the same substance that collects in the ductwork will absorb the odors - that's because the building isn't breathing. Plus, your roof fans are having to work much, much harder. As they do...
