Numerical Study on the Effect of Ball Baffles in Reducing Sloshing Loads in Ship Tanks
Abstract: Sloshing is the free surface motion of a liquid in a partially filled container under periodic motion. Liquid sloshing will result in dynamic pressure on the walls of the container causing large deformations to the tank as well as the supporting structures and carrier. This dynamic pressure on the tank walls due to slosh waves are conventionally mitigated in the tanks of very large crude oil carrier (VLCC) ships by …

Re-Designing Spaces Under Elevated Roads
Abstract: The rapid expansion of elevated road networks in Indian metropolitan cities has significantly improved urban mobility while simultaneously creating extensive underutilized spaces beneath flyovers and elevated corridors. In Mumbai, these under-elevated spaces frequently remain neglected, poorly illuminated, and socially disconnected, often becoming locations for debris dumping, illegal parking, informal encroachments, and unsafe activities. Despite several beautification initiatives, including landscaped gardens, public art installations, and pedestrian walkways, many interventions fail to …
