Numerical Insights Into the Resistance Reduction Mechanisms of Forward Tapered Transoms in High‐Speed Catamaran: A Computational Fluid Dynamics‐Based Study

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT This study investigates the hydrodynamic influence of forward transom tapering on a displacement catamaran hull using computational fluid dynamics (CFD) simulations. Five taper configurations ranging from a vertical transom base design to a fully tapered stern (1.00B) were evaluated over a wide Froude number range (Fr = .3 to 1.0).

Numerical and Experimental Analysis of Total Hull Resistance on Floating Catamaran Pontoon for N219 Seaplanes based on Biomimetics Design with Clearance Configuration

International Journal of Technology, 2020
Seaplanes are planes that can take off and land from the surface of water. Due to their ability to take off and land from the surface of water, seaplanes need a pair of pontoons in the form of a catamaran hull at the bottom of seaplanes so that the ...
