Abstract
Airflow distribution nozzles direct airflow toward a conduit's center upstream of an airflow meter, regardless of the inlet flow orientation. The flow distribution nozzle allows for any flow variation in the intake and produces more laminar flow downstream of the nozzle.
Claims20
A fuel cell air system, comprising:
- a fuel cell;
- a conduit to communicate airflow to the fuel cell;
- an airflow meter positioned along the conduit;
- and
- a nozzle positioned along the conduit upstream of the airflow meter, the nozzle being adapted to direct the airflow to a center of the conduit.
2 more elements
A vehicle, comprising:
- a fuel cell;
- a conduit to communicate airflow to the fuel cell;
- an airflow meter positioned along the conduit;
- and
- a nozzle positioned along the conduit upstream of the airflow meter, the nozzle being adapted to direct the airflow to a center of the conduit.
2 more elements
An airflow distribution nozzle for use in a fuel cell air system, the nozzle comprising:
- a leading diameter positioned along a conduit communicating airflow therethrough, the leading diameter being adapted to receive the airflow;
- and
- a trailing diameter adapted to direct the airflow received from the leading diameter to a center of the conduit before the airflow is communicated to an airflow meter positioned along the conduit.
