Abstract: An aircraft fuel system monitoring apparatus is disclosed having a processor configured to receive first information indicative of one or more parameters relating to fuel present in an aircraft; receive second information relating to the configuration of a fuel system of the aircraft; receive third information indicative of an orientation of the aircraft; receive fourth information indicative of a state of one or more non-fuel-related systems of the aircraft; and generate a prediction of a quantity of fuel present in the aircraft based on the received first information, the received second information, and one or both of the received third information and the received fourth information.

Abstract: A system and method for computing thermal boundary conditions from an unstructured computational fluid dynamics (CFD) simulation for a thermal simulation of a structural component are disclosed. The thermal boundary conditions include convective heat transfer coefficient (HTC) and reference temperature (Tref). In one embodiment, prism cells are formed to capture boundary layer substantially next to a wall of the structural component. Further, tetrahedral cells are formed to capture a diffused temperature layer substantially next to the formed last prism cell and in a direction normal to the wall. Furthermore, temperature of each of the prism cells is computed in the direction normal to the wall until a substantially first tetrahedral cell. In addition, the computed temperature of the prism cell that is substantially adjacent to the first tetrahedral cell is declared as the Tref. Also, the HTC is computed using the obtained Tref.

Abstract: System and method for computing boundary layer properties are disclosed. In one embodiment, a first boundary layer cell that is substantially close to a wall of a structure is selected. A recursive function is then launched for each cell adjacent and around the selected first boundary layer cell to determine a cell having a highest dot product with the normal of the first boundary layer cell. The cell having the highest dot product with the first cell is declared as the second boundary layer cell. The declared cell is selected as the second boundary layer cell. The above steps of selecting, launching and declaring are repeated until a desired number of layers in the boundary layer are completed. The boundary layer properties associated with each selected boundary layer is computed using CFD analysis.
