Based on the results of the gray correlation analysis, it can be concluded that the intermolecular interactions between asphalt and aggregate play a major role in adhesion. The interlocking caused by surface texture also affects adhesion to some extent. The larger work of adhesion and the more complex surface texture of calcined bauxite with higher alumina content are the main reasons for its higher adhesion. Calcined bauxite with low alumina content should be treated to enhance adhesion before it is used in asphalt mixtures for wearing courses.]]> Tue, 26 May 2020 10:16:16 GMT https://trid.trb.org/View/1706866 Coupled vessel and moonpool responses in regular and irregular waves https://trid.trb.org/View/1682895 Wed, 22 Apr 2020 12:27:49 GMT https://trid.trb.org/View/1682895 Numerical investigation on the effect of shaft inclination angle on hydrodynamic characteristics of a surface-piercing propeller https://trid.trb.org/View/1693836 Wed, 22 Apr 2020 12:27:47 GMT https://trid.trb.org/View/1693836 Free-Surface Effects on Interaction of Multiple Ships Moving at Different Speeds https://trid.trb.org/View/1675687 0.2, where , U is ship speed, g is the gravitational acceleration, and L is the ship length), especially when the lateral separation between ships is the order of ship length. Here, the far-field effects arising from ship waves can be important. The hydrodynamic interaction model must take into account the surface-wave effects. Classical potential-flow formulation is only able to deal with the boundary value problem when there is only one speed involved in the free-surface boundary condition. For multiple ships traveling with different speeds, it is not possible to express the free-surface boundary condition by a single velocity potential. Instead, a superposition method can be applied to account for the velocity field induced by each vessel with its own and unique speed. The main objective of the present article is to propose a rational superposition method to handle the unsteady free-surface boundary condition containing two or more speed terms, and validate its feasibility in predicting the hydrodynamic behavior in ship encountering. The methodology used in the present article is a three-dimensional boundary-element method based on a Rankine-type (infinite-space) source function, initially introduced by Bai and Yeung. The numerical simulations are conducted by using an in-house‐developed multibody hydrodynamic interaction program “MHydro.” Waves generated and forces (or moments) are calculated when ships are encountering or passing each other. Published model-test results are used to validate the authors' calculations, and very good agreement has been observed. The numerical results show that free-surface effects need to be taken into account for F n > 0.2.]]> Mon, 23 Mar 2020 12:03:38 GMT https://trid.trb.org/View/1675687 An initial evaluation of the free surface effect on the maneuverability of underwater vehicles https://trid.trb.org/View/1686293 Fri, 28 Feb 2020 10:10:36 GMT https://trid.trb.org/View/1686293 Evaluating the Effect of Binder Aging and Mineral Fillers on Moisture Susceptibility of Asphalt Concrete Using Surface Free Energy https://trid.trb.org/View/1638955 Tue, 28 Jan 2020 09:46:26 GMT https://trid.trb.org/View/1638955 Application of photogrammetry for spatial free surface elevation and velocity measurement in wave flumes https://trid.trb.org/View/1640536 Tue, 24 Sep 2019 14:52:59 GMT https://trid.trb.org/View/1640536 Assessing Moisture Damage of Asphalt-Aggregate Systems using Principles of Thermodynamics: Effects of Recycled Materials and Binder Aging https://trid.trb.org/View/1631880 Wed, 21 Aug 2019 09:35:47 GMT https://trid.trb.org/View/1631880 The Impact of Free Surface Modelling on Hydrodynamic Forces for Ship Navigating in Inland Waterways: Water Depth, Drift Angle, and Ship Speed Effect https://trid.trb.org/View/1606465 Mon, 22 Jul 2019 10:32:22 GMT https://trid.trb.org/View/1606465 Slamming load on trimaran cross section with rigid and flexible arches https://trid.trb.org/View/1606016 Thu, 27 Jun 2019 14:53:56 GMT https://trid.trb.org/View/1606016
