  • Patent number: 10766065
    Abstract: A component is formed from a component material introduced into a mold assembly. The mold assembly includes a mold that has a cavity defined therein by an interior wall. The cavity receives the component material in a molten state to form the component. A multiple component core assembly is positioned with respect to the mold and has a first core component attached to a second core component at a core split line. A core connection component is attached to each of the first and second core components at the core split line, such that the first core component is held adjacent the second core component at the core split line. The core connection component is formed from a connection component material that is at least partially absorbable by the component material.

  • Publication number: 20200218232
    Abstract: According to some embodiments, an operating environment measurement of an industrial asset may be received from at least one sensor. A high-fidelity physics-based model may represent operational performance of the industrial asset and the performance's dependency on the operating environment measurement. A surrogate model creation engine may automatically create a surrogate model of the industrial asset based on the operating environment measurement and results from the high-fidelity physics-based model. An optimization platform may receive the surrogate model and use the surrogate model along with an optimization algorithm to generate a set of optimized fluid flow control system parameters for the industrial asset. In this way, a fluid flow control system may be designed to improve the performance of the industrial asset.

  • Publication number: 20200042659
    Abstract: According to some embodiments, a surrogate model creation computer system includes a user interface to interact with a subject matter expert to create a scripted physics-based model workflow associated with an industrial asset. The surrogate model creation computer system further includes a surrogate model creation engine to automatically execute the scripted physics-based model workflow, in connection with a physics-based model of the industrial asset, to generate at least one response surface of the physics-based model workflow. The surrogate model creation engine may then use the response surface and a machine learning process to automatically create a surrogate model of the industrial asset. It may then be arranged to output the surrogate model for use by a substantially real-time analytics package associated with the industrial asset. According to some embodiments, scripting for a physics-based model workflow may also be automatically created.

  • Patent number: 10421119
    Abstract: A method of forming a component including coupling an array of receptacles to a mold core. Each receptacle in the array contains an amount of uncured mold material. The method further includes forming a layer of fugitive material on the mold core such that the array of receptacles is encapsulated within the layer of fugitive material. The method also includes forming a layer of uncured mold material on the layer of fugitive material, thereby forming an uncured mold assembly. The uncured mold assembly is heated to a temperature that solidifies the uncured mold material within each receptacle and of the layer, thereby forming an array of pins and a layer of solidified mold material. The uncured mold assembly is also heated to the temperature that removes the layer of fugitive material from between the mold core and the layer of solidified mold material such that a mold cavity, including the array of pins, is defined therebetween.
