Simulation and Data Utilization in Digital Age

In the past decade society has undergone a digital shift, in which many economic fields have come to depend more and more on digital techniques, such as AI, Big Data, Simulation, etc. In this talk, we will discuss digitalization of society which is accelerated by AI technologies. We will also introduce some recent development of AI technology such as Deep Learning and Data Analysis as well as examples of large-scale simulations.

Saving Potentials using Alsim Paint Shop Simulations 

Using Alsim Paint Shop simulations, customers can improve painting quality and optimize painting costs. Savings include: 1. Optimized design for new products (simulate the painting quality of new products in design phase and to get suggestions how to change the design for the best painting quality and reduce costly prototypes and physical tests), 2. Optimized operating painting lines (enhance overall performance of operating painting lines, to minimize energy, water and paint consumption, to find the real source of problem in case of flaws in the final products to reduce the rate of production line-stops for repair or maintenance purpose), and 3. Optimized design for new painting lines (avoid a wide range of potential operation issues, simplify the entire process flow by optimizing different stages regarding elapsed time or space, and to minimize energy, water, and paint consumption).

Managing Different Levels of Fidelity in CFD using Data Fusion

During the design and optimization of vehicles, their aerodynamic characteristics are typically obtained by experimental-based wind tunnel tests and high accuracy CFD simulations. Both methods come at a cost, either being economically or computationally expensive. Alternatively, the computational intensity of CFD simulations can be reduced by combining lower fidelity CFD models and methods with high accuracy variants. In this presentation, such methodology is introduced based on a data fusion algorithm. Using Optimus for Cradle, automated CFD workflows are created that generate both the low and high fidelity data. Next, by running the data fusion algorithm, the accuracy of the low fidelity CFD calculations can be significantly improved by adding a small set of expensive CFD experiments. An important aspect of data fusion is determining where the additional high fidelity CFD experiments should be added. This presentation outlines the application of such a data fusion process using Optimus.

Computational design with Grasshopper and scSTREAM for Integrated Design

Grasshopper enables flexible development by allowing geometry change, which was conventionally difficult. For this reason, the tool has been applied in diverse range of industries and used in integration with 3D-CAD and analyses. Seeing the advancement taken place worldwide, the expectation for CFD is also significant. Following the trend, we have combined Grasshopper and scSTREAM to reinforce database linkage, analysis automation, and Postprocessor handling.

Application Case of Nozzle Jet in Arc Spraying using Density-Based Solver

Arc spraying is a type of coating technology that performs surface modification by applying anode and cathode between two metallic wires to trigger arc discharge to let metal melt. Melted particles are then sprayed onto object surface by nozzle jet air. This session will briefly introduce our attempts in evaluating jet stream phenomenon of nozzle using density-based solver in scFLOW V14.1, which in part was undertaken in pursuit of establishing a new technique to control fractionating melted particles and regulate jet stream from nozzle.

Flow analysis of sprinkler in large cooling tower for industrial use

Cooling tower uses outdoor air to cool down and reuse a large amount of heated water, which was previously used in industrial facilities, such as manufacturing plant, power generation plant, and air-conditioning facilities. Considering its made-to-order characteristic, and that facility scale is significantly large, prototyping is difficult, and simulation is a vital means of validation. This session will introduce how we performed flow analyses of sprinkler system for cooling tower in Japan’s largest geothermal power plant.
