IHI ENGINEERING REVIEW
IHI and Soma City (Fukushima Prefecture) have jointly launched a demonstration research facility — a pioneer to a “smart community” aiming to produce, store, and smartly use energy, not just consume it. Soma IHI Green Energy Center started an initiative for local production of energy for local consumption.
Ocean current power generation is a harvesting method of ocean renewable energy. This energy regeneration technology is intended to effectively utilize the Kuroshio Current and is suited to Japan. In August 2017, IHI and New Energy and Industrial Technology Development Organization (NEDO) conducted a demonstration experiment of the world’s first 100 kW-class ocean current turbine located off the coast of Kuchinoshima Island, Kagoshima Prefecture and obtained data for commercialization.
Recently, labor shortages are an urgent issue in the logistics sector. Now, IHI has developed and has started selling a new robot system for logistics-related tasks, particularly a system for depalletizing (unloading boxes from a pallet) operations that require heavy work.

The use of more electric aircrafts will improve safety, ecology and economic benefits through innovations designed to integrate their power and thermal management. Under this concept, high power generation is the crucial issue. The More Electric Architecture for Aircraft and Propulsion (MEAAP) consortium is working with IHI to exploit the electrification system for future engines and aircrafts over the next decade or two. This paper introduces the latest resolution approach developed by IHI and the results of Japanese interactive open innovation.

Aeroengine parts are produced by carrying out casting, powder metallurgy, and plastic forming techniques such as forging. Forged products usually have little variation in terms of strength so this method is applied when a high degree of reliability is needed. In addition to the product’s dimensions and strength, requirements are also set with regard to the quality of the microstructure if a particularly high degree of reliability is required. Based on these requirements, IHI is developing a new microstructure prediction model that takes into consideration the physical mechanism that occurs during the forming process in order to accurately simulate the microstructure evolution. This paper discusses crystal-plasticity finite element method (CPFEM) simulations, which form part of the new model.

A pilot plant for a Carbon Capture and Storage (CCS) facility was designed by utilizing a reaction rate-based process simulation technology. The targeted energy consumption was achieved in the pilot plant tests, but the carbon capture performance was much higher than the simulation results. Based on the data obtained in the tests conducted at the pilot plant, the simulation model was improved to the point where the results matched the test data. In the future, this simulation model will be further improved and utilized in developing designs for demonstration and commercial plants.

Recently, High-Temperature Superconducting (HTS) appliances have been transitioning from the research phase to the product development stage. A turbo-Brayton refrigerator that uses neon gas as its working fluid is considered to be suitable for the cooling of large-scale equipment such as HTS cables. The reason for this is its compactness and high capacity, as well as its high reliability during long-term operation and relatively easy maintenance owing to its oil-free nature. IHI has been working with TAIYO NIPPON SANSO CORPORATION on the development of such a turbo-Brayton refrigerator since 2006. This report describes the CFD analysis that is used in the aerodynamic development of the turbines and compressors that constitute the refrigeration system.
