Force of Water Waves on an Obstacle

Obstacle avoidance for an autonomous vehicle using force field method

This paper presents a force field concept for guiding a vehicle at a high speed maneuver. This method is  similar to potential field method. In this paper, motion constrains like vehicles velocity, distance to obstacle and tire conditions and such lane change conditions as zero slop condition and zero lateral acceleration are discussed. After that, possible equations as vehicles path ar...

Numerical simulation of capillary gravity waves excited by an obstacle in shallow water

Capillary gravity waves excited by an obstacle are investigated by numerical simulations. Under the resonant condition for which large-amplitude solitary waves are generated, solutions of the Euler equations show that the capillary effects induce the generation of short waves both upstream of the solitary waves and downstream of the obstacle. Overall characteristics of these waves agree with th...

Estimation of Lift Force on a Rough Vertical Pile of Platform to Random Sea Waves

Similar to random sea waves, forces on the offshore structures due to waves are random. These forces can be mainly divided into two components, namely, inline forces and transverse or lift forces. The random nature of lift forces is more complicated than that of inline forces and both should be combined for design purposes. In the present paper, two different approaches have been used to determ...
