A web-based platform is developed for researchers to obtain flame characteristics using a web browser. The platform uses open-source chemical kinetics software and command –line client web application: Cantera, Ember, and Jobson. The platform calculates flame characteristics such as flame speed, flame temperature, emission, and more for premixed and diffusion flames. Various fuel/oxidier compositions and various chemical mechanisms are available, and more compositions and mechanisms are planned to be included.

This report surveys recent developments of carbon-neutral gas turbine combustion technology. Since the Paris Climate Agreement in 2019, each country committed a nationally determined contribution (NDC) which identifies key targets to reduce the temperature rise. In order to meet the NDC, each government is pushing hard to reduce greenhouse gas emissions, and using carbon-neutral fuel is a straightforward way to reduce to achieve the goals. As carbon-neutral fuels such as hydrogen or ammonia have different thermodynamic and transport properties, it needs paradigm changes in many related sectors. Gas turbine is one of the sectors, and this report reviews ongoing progress and challenges centered around developing carbon-neutral gas turbine combustion technology.

We propose a method for the implementation of an EtherCAT communication bus in a Linux-based open source Computerized Numerical Control (CNC) system. Recently, increasingly more CNC systems support real-time Ethernet protocols such as EtherCAT, which is a high-performance industrial communication protocol. For real-time CNC control over an Ethernet-based protocol, an additional layer driver needs to be implemented between the CNC system and the master of industrial communication protocol. Among the various solutions for the connection layer driver, we employ a Hardware Abstraction Layer (HAL) driver based on Linux. The operation of the implemented CNC system is demonstrated and confirmed by Hal Meter, which is used to observe the pins, signals, or parameters of HAL.
