the aim of this manuscript is to study the implication of aluminium-oxide nanofluid for an amphibious vehicle engine (viable on land and under water) cooling system both analytically and experimentally. to achieve this, a one-dimensional model of the engine cooling system (radiator) is considered through a computational fluid code in which the mass flow rate for a range of the coolant temperatu...

In order to evaluate the waterborne performance of amphibious vehicle, based on Fluid Dynamics and principle of marine mechanics related knowledge, the resistances and viscous flow field of amphibious vehicle in different headway were numericaly simulated by solving Navier-Stokes equatlons with the k ε − turbulence model. we obtained the result of frictiona resistance coefficient 、 residual res...

The development of amphibious robots requires actuation that enables them to crawl as well as swim; sea turtles are excellent examples of amphibious functionality, that can serve as the biomimetic model for the development of amphibious robots. In this paper we have implemented the observed swimming kinematics of Myrtle, a green sea turtle Chelonia Mydas residing in the Giant Ocean Tank of the ...

This paper presents the modelling of an autonomous amphibious vehicle developed at the Australian Centre for Field Robotics, Sydney. All parts of the vehicle’s driveline from the engine, CVT, gearbox to wheels are analysed and modelled. Results from simulation, compared with data from characterising experiments, show that these models are valid and can be used for the control purpose. Keyword: ...

The capability of a commercial off-the-shelf amphibious bottom crawling robot is explored for surveying seamless topography and bathymetry across the beachface, surfzone, very nearshore. A real-time-kinematic (RTK) antenna on mast was added to robotic platform, Bayonet-350 (previously C2i SeaOx). Data collected from were compared with those by Coastal Research Amphibious Buggy (CRAB) Lighter Re...

This paper presents the design and development of the software and control architecture of the Centaur, an autonomous amphibious and all-terrain utility vehicle project. The adaptation of a hybrid between planning and behaviour based control architectures for the vehicle is explained using decomposition methods. This paper will show how subsystems relate and operate with each other to accomplis...

The practical application of the Computational Fluid Dynamics (CFD), for predicting the flow pattern around Multipurpose Amphibious Vehicle (MAV) hull has made much progress over the last decade. Today, several of the CFD tools play an important role in the land and water going vehicle hull form design. CFD has been used for analysis of MAV hull resistance, seakeeping, maneuvering and investiga...
