27. Problem Area: Ship hydrodynamics (title Confidential)

Project Role:                  Principal investigator

Project Value:                S$35,000.

Duration:                       2001-2002.

Client:                           Singapore Navy.

Project Details:

The multi-body interaction of a submerged floating body, of the size of a human, with a mine-hunting ship has been investigated.  The safety of the mine-hunting sonar equipment is in question.  This work aimed at prediting the trajectories of the submerged body while it approaches the ship from the front.  Current and wave effects were considered.  The studies suggested the possible position and configuration of a deflector structure for the sonar array.

28. Problem Area: Ship Hydrodynamics and Berthing Manoeuvre (title Confidential).

Project Role:                  Principal investigator
Project Value:                S$60,000.

Duration:                       1 Year.

Client:                           Singapore Navy.

Project Details:

Movement of several naval ships were considered in a naval base.  The study aims at optimising the space between some proposed new facilities.  Naval ships of several tonnages were considered, starting from destroyers to mini-subs.  The hydrodynamics of the bodies were simulated by strip theory.  The traffic is controlled by a Swedish code named PORTSIM.

30. CFD studies on sedimentation in a Clarifier.

Project Role:                  Team member
Project Value:                S$47,000.

Duration:                       6 Months.

Client:                           Binnie-Black & Veactch (USA).

Project Details:

Sediment motions in a clarifier in a watrer treatment plant is considered.  The sediment movement is predominantly characterised by inlet velocities and the movement of a scum scrapper in the clarifier.  3D CFD simulations were conducted to optimise the design of a drum that streamlines the flow in the clarifier.

31. Computer Simulation of a “White” Water Phenomenon.

Project Role:                  Principal investigator
Project Value:                S$5,000.

Duration:                       1 Month.

Client:                           Public Utilities Board, Singapore.

Project Details:

This project aims at studying the levels of air-ingress in a water main due to a change in the state of operation.  Due to varying air-ingress levels, at different times of the day, the water distribution system may have a white coloured water.  The study predicted the percentage of air in the water distribution system and characterises the behaviour of air pockets at various parts of the water main.

32. Improvement of Flow conditions in the Machilipatnam creek (India).

Project Role:                  Senior Project Officer

Project Value:                Unknown.

Duration:                       More than 1 Year.

Client:                           Machilipatnam Port.

Project Details:

Machilipatnam creek in a major shipping channel for fishermen in the area.  Vessels travelling along the channel encountered navigational problems. It has been established through numerical model simulations that formation of multiple eddies of the scale of half the channel width complicated navigation of vessels.  These eddies were in-turn caused by the flow from a side canal from the north that caused the south bank to erode.  Mitigation measures were suggested based on numerical model studies with modified channel geometries.
