Research, simulation and measurement

Research & Development (R&D)

Getting to the bottom of engineering problems that need simulation, measurement or deeper verification. From a specific question or hypothesis, LASAN MARINE chooses the right method — CFD, structural analysis, measurement, testing or data analysis — to clarify the problem and check it against real data where possible.

What do you need to find out?

I need to compare hydrodynamic options

When the effect of a change in geometry or operating condition can't be judged by eye, CFD can compare resistance, flow field, loads and related quantities.

See related research

I need to check the flow or cavitation around a propeller

Simulation can show the pressure and velocity distribution and the unfavourable flow regions, to support the assessment of a design.

See hydrodynamics research

I need to check structure or vibration

Numerical analysis identifies stress, deformation, vibration characteristics and the areas that need closer checks under specific load cases.

See structural research

I need to verify with real data

LASAN MARINE can measure geometry or real operating parameters to compare against the design and check how well the calculation model fits.

Discuss the deliverables

Simulation results depend on the quality of the model

LASAN MARINE controls geometry, mesh, boundary conditions and convergence criteria. Where measured data or reference results exist, they are used to validate the model. The report also states the assumptions and the limits of the results.
