Description
The Virtual Formulation Laboratory (VFL) is a computational tool (based on empirical modelling) developed to simulate and optimise the behaviour of complex particulate systems. While initially designed for bulk solids handling in terrestrial manufacturing, the technology offers a framework for modelling and analysing lunar regolith simulants, addressing critical challenges in extra-terrestrial dust characterisation and handling.
This study proposes the adaptation of the VFL to predict the behaviour of lunar regolith simulants under various reduced gravity conditions and environmental constraints. By incorporating parameters such as particle morphology, cohesion, adhesion, and electrostatic properties, the tool supports virtual testing of regolith characteristics, including flowability, caking, particle breakage, and dust adhesion—key factors affecting mission-critical systems such as mobility platforms, life support systems, and scientific instrumentation.
The VFL can be employed for:
• Characterisation and simulation of dust/regolith behaviour under lunar conditions
• Development and optimisation of regolith simulant formulations to mimic certain features of site-specific lunar soils
• Assessment of contamination risks to materials and mechanical components
• Support for dust mitigation strategies through virtual testing
• Design of dust testing protocols within simulated lunar environments
By building a physics-based knowledge database and integrating empirical data from existing simulants, the VFL can help researchers and engineers better understand the interactions of lunar dust with systems and surfaces. This supports early-stage decision-making for material selection, equipment design, and mission planning—ultimately reducing costs and improving the reliability of lunar operations.
