Wind Farm Control (WFC) is defined as the coordinated control of the turbines in a wind farm, influencing the flow between the turbines as well as the power supply to the electricity system. Its primary goal is to mitigate the wake effects that reduce velocity and increase turbulence behind the turbine(s), while maintaining the stability in the grid.

Contact electrification (also called tribocharging) results from the exchange of electrostatic charge during frictional contacts between same-type or different materials.

Recent earthquakes evidenced that many building structures may have a poor performance in future seismic events.

In this talk, we will describe the system development approach followed by researchers and engineers of the team NAIST-RITS-Panasonic (Japan) for our participation in international robotics competitions such as the Future Convenience Store Challenge (2018 to 2022).

Gas-liquid membrane contactor (GLMC) uses hydrophobic porous membrane to separate gaseous feed and liquid absorbent is one of the cost-effective post-combustion carbon capture technologies due to its excellent selectivity and lower energy requirement. Unfortunately, GLMC suffers from membrane wetting, toxic amine usage and energy- intensive solvent regeneration process.

The use of detailed chemistry is becoming an essential requirement in CFD simulations of complex reacting flows, such as the Moderate or Intense Low-oxygen Dilution (MILD) combustion regime. However, detailed kinetics mechanisms often require to solve hundreds of ordinary differential equations per computational cell, causing the need for massive computational resources.

Natural circulation is a key issue in the design of chemical plants and nuclear power stations for simplicity, inherent safety, and maintenance reduction features. Those natural circulation systems are susceptible to flow instability, science the driving force of circulation is sensitive to momentum and energy balances.

Wall-modeling in LES is of high importance to allow the scale-resolving simulation of industrial-scale applications. Numerous models were developed and validated for incompressible flows, including a simple quasi-analytical model based on the Reichardt formula. This work presents a new scaling of this formula to properly take the compressibility effects into account.

Many countries worldwide are developing energy strategies to reduce reliance on fossil fuels and cut CO2 emissions to avoid the worst effects of climate change. Most models we use to support this decision-making process rely on very uncertain long-term forecasts for important parameters, such as fuel prices and energy demand.
