Hydrodynamic Resistance Reduction in Catamaran Assisted Hydrofoils
The present paper contains the test results of a planing catamaran model. The aim of the tests was to study the effect of hydrofoil in these types of crafts. First, experiments were carried out on the bare body (i.e. without hydrofoils) to obtain non-dimensional hydrodynamic resistance coefficient versus speed. Then, the model with hydrofoils, by various locations and attack angles were subject...

متن کاملNumerical simulation of three-dimensional flow around two circular cylinders in tandem arrangement
Three-dimensional fluid flow around two circular cylinders in tandem arrangement is computed by the finite difference method without a turbulence model. The overlapped grid technique is employed to catch the flow interference between the two tandem cylinders. It is confirmed that the abrupt numerical change of drag coefficients and the Strouhal number is in good agreement with the previous expe...
متن کاملNumerical simulation of nanofluid flow over diamond-shaped elements in tandem in laminar and turbulent flow
In this paper, the Al2O3-water nanofluid flow in laminar and turbulent flows inside tubes fitted with diamond-shaped turbulators is numerically modeled. The nanofluid flow is modeled by employing a two-phase mixture method and applying the constant heat flux boundary condition at tube walls. In the results, the effects of different parameters such as the geometry of turbulators, volume fraction...
متن کاملNumerical simulation of hydrodynamic properties of Alex type gliders
Simulation of an underwater glider to investigate the effect of angle of attack on the hydrodynamic coefficients such as lift, drag, and torque. Due to the vital role of these coefficients in designing the controllers of a glider and to obtain an accurate result, this simulation has been studied at a range of operating velocities. The total length of the underwater glider with two wings is 900 ...
