Thermal Response Tests (TRTs) are widely used for conventional borehole heat exchangers to estimate ground thermal properties and support geothermal system design. However, their direct application to some specific energy geo-structure elements is not straightforward, such as retaining ... En savoir plus

Borehole Thermal Energy Storage (BTES) can play an important role in the decarbonization of heating by storing surplus renewable or waste heat over seasonal timescales. However, the performance of a BTES system depends strongly on the borefield configuration, including borehole spacing, ... En savoir plus

The chemical industry faces increasing pressure to reduce energy consumption and greenhouse gas emissions. Traditional reactor designs often require external heating or cooling, leading to significant energy losses. A promising approach is the dual-flow reactor, which integrates an ... En savoir plus

Green14 is developing a new, lower-impact technology for producing metal powders for additive manufacturing. From the start, the process is paired with a Physics AI loop rather than the traditional empirical FEM approach: the physical model itself is learned through a reinforcement ... En savoir plus

In long industrial furnaces equipped with multiple ON/OFF burners, achieving a prescribed heating ramp while maintaining acceptable temperature uniformity is challenging because radiation and forced convection interact with strongly time-dependent heat input. This work presents a COMSOL ... En savoir plus

In the context of pure oxygen storage and transportation, such as production facilities, spacecraft propulsion systems, and medical oxygen supply, severe accidents still occasionally occur. These incidents, including facility damage, storage tank explosions, and even the complete loss of ... En savoir plus

We present the development of a micro gas generator (see Fig. 01: Schematic of the micro gas generator), engineered to deliver controlled analyte pulses in the ppb–ppm range via permeation through porous polymer membranes. The device incorporates four micro‑reservoirs embedded within a ... En savoir plus

Induction heating of moving metallic charges is widely used in industrial processes requiring precise control of thermal exchanges. A core issue is to ensure both thermal homogeneity and sufficient exposure of all material points to temperatures above the melting threshold during the ... En savoir plus
