PSC motors are only used in those applications where the airflow
from the FPTU fan is expected to be constant.
Since the air is supplied at relatively low velocities (25 to 35 fpm, 0.13 to 0.18 m/s) and only through a part of the ceiling, the unidirectional flow can be maintained mostly in the core of the air jet; whereas, in the other regions of the room recirculating airflow
patterns are formed, including at the periphery of the supply air jet (Khankari 2017a, Khankari 2017b).
The application of electronically commutated motors (ECMs) into series FPTUs has made it possible for engineers to specify FPTUs that can provide significant energy savings over fixed airflow
Figure 8 presents the relationship between the aerodynamic resistance and airflow
distribution ratio when the airflows
in the 8-channel cyclone are regulated by quarter-rings without holes.
Using flow designing fluid simulation software Solidworks Flow Simulation flow analysis of symmetrical and asymmetrical profile blades at different airflow
velocities was performed.
The test object is instrumented with a sensitive balance to measure the forces generated by airflow
; or, the airflow
may have smoke or other substances injected to make the flow lines around the object visible.
Iteration 1 reduced the percentage of satisfactory ASTM metrics by 7%, but further tuning of the model with diffuser airflows
in iterations 2 and 3 increased it by 28%.
The Teflon airflow
distributor allows the container to run in contact with the surface and this can be customised to suit the line speed and container, in order to achieve maximum cleaning.
In general, airflow
can be analyzed using three types of methods: experimental, theoretical, and numerical simulation.
Keeping pace with the ever changing finishing market, Airflow
has developed a comprehensive product range to meet the varied requirements of companies involved in powder coating.
The basic difference between left- and right-nostril sniffs depends on airflow
, explains Noam Sobel of Stanford University.
However, the air temperatures (Figures 3 and 6) and total airflows
(Figures 4 and 5) are different between the two limits.
