Here is what we at Cloud Towing Tank cannot help you with: Design a hull form based on project requirements from scratch. We are not hull designers, we do not have the knowledge, experience or tools to do that. Here is what we can help you with: 1. Optimise your hull design by changing its local or global shape parameters. We use CFD and parametric hull deformation to do that. 2. Evaluate your design in terms of resistance, propulsion, seakeeping and manoeuvring using CFD. www.cloudtowingtank.com #cfd #hydrodynamics #optimisation #parametricoptimisation #efficiency #shipdesign #navalhydrodynamics #propeller #selfpropulsion #navalarchitecture #thenavalhydropack #cloudtowingtank

A CFD hydrodynamic simulation service for the marine industry. Helping design more efficient ships.
About us
The Cloud Towing Tank is a unique set of services that provide quick and accurate CFD simulations of most essential phenomena in marine industry. The foremost of these is the Calm Water Resistance, as well as Self-Propulsion simulations, providing information about the resistance and propulsion power requirements for a ship. Whether you are a naval architect designing a ship, or a ship operator looking to reduce the fuel consumption, we can provide you with essential information that will help you make informed decisions about the future of your project or fleet. The key feature of our service is quick response and accurate results, which fit well into a ship design process, or a dry-dock plan scheduled. For ship/yacht/boat designers, contact us if you need to test different options for your geometry and to see the impact of changes to the ship's performance. For ship owners/operators, let us know if you want to conduct a trim-optimization study in order to reduce operational costs, make informed decisions about dry dock activities, or if you simply need a baseline fuel consumption data for your ships. What separates us from most service providers is the fact that we use a CFD software we helped develop, enabling us to automate and optimize every step of the process, providing a fast and affordable computational service.

"Simulating maneuvering in waves using CFD and comparing the results against model tests." That in short is what the freshly published paper is about - read more below!
Our latest research article has just been published, focusing on maneuvering simulations of an ONRT surface combatant ship using advanced Computational Fluid Dynamics methods. The study compares the actuator disc model with the partially rotating grid method, offering insights into these approaches' accuracy and computational efficiency in simulating complex maneuvers like turning circle and zig-zag, in calm water and head waves. The partially rotating grid method combines a fully time-resolved approach with dynamic overset grid technology and the multiple reference frames (MRF) approach, integrating the strengths of both methods. The MRF allows for larger time steps, conserving computational resources, while the time-resolved approach provides the time-varying position of propeller blades. This method effectively captures the critical propeller side force, often overlooked in simpler models, resulting in more precise predictions of ship behavior during maneuvers. Special thanks to Prof. Hrvoje Jasak for his mentorship and invaluable advice, and to the team from Cloud Towing Tank for their much-appreciated contribution in publishing this research.

Predicting seakeeping characteristics of fast crafts can be challenging. CFD can be used to conduct irregular wave simulations to calculate accelerations, speed loss, and possible wave slamming loads acting on the vessel. Below is an example of a Crew Transport Vessel sailing at roughly 30 knots of speed in head irregular waves. www.cloudtowingtank.com #cfd #hydrodynamics #optimisation #seakeeping #efficiency #shipdesign #navalhydrodynamics #propeller #selfpropulsion #navalarchitecture #thenavalhydropack #cloudtowingtank #semidisplacementhull

Some interesting and some expected findings from a parametric CFD optimisation of a round-bilge semi-displacement hull: Expected: Moving the LCB towards amidship lowers resistance at lower speeds, moving it aft lowers resistance for Froude numbers approaching 1.0. Interesting: Deeper transom benefits higher Froude numbers, shallower draft benefits lower Froude numbers. Reducing transom width slightly reduces resistance at high Froude numbers.
