Definitions

  • a heat exchanger includes inlet structures that distribute flow from a circular conduit into one or many smaller flow passages.
  • High initial total pressure with the inlet manifold is desired to be maintained, with minimal loss, through the heat exchanger and out the exit manifold.
  • Flow Velocity within the relative large spaces provided by the manifold are relatively low compared to airflow velocities desired within the smaller flow passages where thermal transfer occurs.
  • Higher airflow velocities through the flow passages increase thermal transfer efficiencies.
  • Pressure losses between the conduit, manifold and the smaller flow passages can be substantial and reduce airflow velocity and thereby thermal transfer efficiencies.
  • the airflow expands into the larger space that generates further pressure losses.
  • the combined pressure losses at the inlet and the outlet reduce thermal efficiencies and require structurally larger heat exchangers to accommodate increased demands.
  • Turbine engine manufactures utilize heat exchangers throughout the engine to cool and condition airflow for cooling and other operational needs.
  • Turbine engine improvements have enabled increases in operational temperatures and pressures. The increases in temperatures and pressures improve engine efficiency but also increase demands on all engine components including heat exchangers.
