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 …

Enhancing the Heat Transfer in the Thermal Chimney by Attaching the Fin under CFD Analysis
Abstract: The primary and secondary heaters in heat exchangers were numerically evaluated at nominal temperatures of 140°C for the primary heaters, 100°C for the secondary heaters, and 20°C for the ambient temperature in order to validate the design idea for enhancing the air temperature. The “convective heat transfer” of air in a thermal chimney built to laboratory size using two different types of electrical heaters and a rectangular cross-section of constant …
