  • Patent number: 10670438
    Abstract: In order to measure a fluid flow or flow conditions of a fluid flow through an apparatus, electrodes are provided across which capacitance values are determined. The capacitances are used in conjunction with a predetermined model to determine a revised model for the system. If the modelled to be satisfactory, then the values representative of the flow conditions are output. If it is not, then the model is tuned to reduce the error. A novel arrangement of electrodes is also provided along with apparatus embodying the method. The invention also provides a way of determining fluid properties, for example, density, volume present contained within a vessel or tank whether flowing or stationary.

  • Patent number: 10671768
    Abstract: An apparatus is provided for predicting propagation of a crack in a structure. A finite element model is provided that represents the layers of the structure by meshes of elements having interfaces defined between adjacent elements in orthogonal potential crack planes. Overlapping interface elements are defined at the interfaces and include a plurality of node pairs spaced apart along multiple interfaces and having a node cluster therebetween that includes bound node pairs. The nodes of each node pair are coincident with respective nodes of the adjacent elements on opposite sides of the interface. An analysis of the finite element model under an external load is performed in which a crack tip is established at a node cluster. A strain energy release rate between the nodes of the bound node pairs of the node cluster is calculated and based thereon propagation of the crack is identified.

    Abstract: Aspects of the present invention provide a solution for calibrating a model of a complex flow system. In an embodiment, a comparison is made between the output from the model and a set of observed values for each of a plurality of nodes in the complex flow system. An adjoint sensitivity is computed for each of the nodes based on the comparison. These computed adjoint sensitivities are used to adjust a set of coefficients of the models. This calibration process can be performed multiple times, periodically and/or continuously to maximize the accuracy of the model.
