The potential for acoustic metamaterials to provide a breakthrough in sound attenuation has been unlocked recent times due advancements additive manufacturing techniques. These materials allow the targeting of specific frequencies attenuation. To date have not experimentally tested an automotive silencer performance enhancement. This study investigates effect within representative silencer. res...

Propellant slosh is a potential source of disturbance critical to the stability of space vehicles. The slosh dynamics are typically represented by a mechanical model of a spring mass damper. This mechanical model is then included in the equation of motion of the entire vehicle for Guidance, Navigation and Control analysis. Our previous effort has demonstrated the soundness of a CFD approach in ...

Water is one of the world’s most valuable resources. However it is under constant threat due to urbanization, explosive population growth and pollution. The most promising efforts to stem water crisis are to treat the wastewater in a sustainable way and reuse for non-potable applications. Grey water (GW) being highly voluminous and relatively less polluted, recycling for non-potable uses like u...
