Computational Fluid Dynamics

We exist in a world of motion, a world of fluid mechanics.  Every movement you make interacts with fluids.  Walking down a corridor, air flows around you.  Your body heats the air over your head, which rises to the ceiling.  A boiling tea kettle introduces water vapor, which disperses and changes the air concentration.  A ship turning in a channel may experience water flow around the hull, recirculation near the propeller shaft, and separation at the rudder blade.  Every aspect of change in our world gets shaped by fluid mechanics.  Given its pervasive presence, you need the ability to predict and control fluid mechanics.  Don’t let the wind and wave control you; work around them.

Computational fluid dynamics (CFD) is a mature technology that allows engineers to understand, predict, and work with fluid mechanics.  The flow of wind and waves around buildings and ships can be fiercely complicated, requiring extremely complex mathematics to predict.  CFD captures those mathematics in computer programs and allows almost unlimited flexibility.  At DMS, we can answer almost any question about fluid flow:

  • Wind loads analysis
  • CFD motions simulation
  • Offshore structure loads
  • Seabed sediment scouring
  • Calm water resistance study
  • Wave slamming forces
  • Tank sloshing loads
  • Channel flow studies
  • HVAC design for open spaces
  • Hydrofoil design
  • Rudder design
  • Roll damping design

But CFD is not without its price.  Without careful management, CFD rapidly gets expensive.  DMS works diligently to limit our costs and keep CFD accessible for you: 

  • We avoid expensive licensing fees.
  • We minimize computing costs by building our own hardware.
  • As a general rule, we don’t even charge for validation studies.
  • At DMS, your only major cost is the skill of the engineer.

Reliable CFD requires certain skills.  Without the experience and skill of our engineers, CFD just becomes colorful garbage.  At DMS, we prove our quality.  We perform validation studies on our own time.  Every project gets a mesh independence study.  Before we even begin your production runs, we can estimate the margin of error in the simulation.  This is the science of CFD.  The rigors of proof to ensure reliability.

Hydrodynamics and Hull Design

A refined hull shape epitomizes the link between tradition and science. When we link the science of ship design with the experience of past ships, we identify the successes and isolate previous failures. This article glimpses into the background of hydrodynamics by exploring the link between the science of Bernoulli’s equation and the shape of ship hulls.

Video: Selecting the Right Hullform

Monohull, catamaran, trimaran . . . so many choices. Which hullform to pick? Can we draw upon any science to guide our choices, or we beg Lady Luck to guide us? This article provides a rational and design map for selecting hullforms applicable to any type of mission. This organized approach allows us to see past the limitations of historic examples and consider new alternatives.

Go FAST Boat: Pros and Cons of a Planing Hull

ZOOM!!!  No better way to describe planing boats.  They pack very fast speeds into a very small package.  Many planing boats achieve speeds well beyond the limits of larger craft.  How do they do it?  And what are the penalties for this extreme speed?  Discover if a...
