Airflow - Wikipedia

Types of airflow. Like any fluid, air may exhibit both laminar and turbulent flow patterns. Laminar flow occurs when air can flow smoothly, and exhibits a parabolic velocity profile; turbulent flow occurs when there is an irregularity (such as a disruption in the surface across which the fluid is flowing), which alters the direction of movement.

Mass flow sensor - Wikipedia

At the simplest level, an airflow sensor, or more precisely a mass air flow sensor, is a device with two pressure ports where gas flows from one port to the other (see Figure1). Inside the sensor, there’s a sense element with a heated surface. As gas flows across the sense element, heat is transferred from upstream to downstream, asshown in Figure 2. This creates a thermal imbalance proportional to the …

Flow Sensor - an overview | ScienceDirect Topics

The air flow sensor measures the amount of air intake into the engine. On the basis of the signals of the air flow sensor, the ECU determines an adequate rate of fuel injection. In the 1970s, a vane-type air flow sensor, which used the phenomenon of plate displacement that occurred depending on the amount of air, was developed. In the 1990s, the hot wire sensor was developed as shown in
