Hydrostatics and Hydrodynamics Analysis
for Amphibious vehicle or Ship
For water vehicle design, CFD analysis can be used for:
- Calculating wetted volume of vehicle part based on total weight of the vehicle and bouyancy force of the wetted volume.
- Distributing wetted volume of the vehicle to meet specific vehicle attitude while floating on water. This can be done by additional floating device too.
- Optimizing hull design to minimize wave drag and viscous drag.
- Optimizing position of propellers to reduce potential waterflow blockage.
- Optimizing propeller shape for maximum force.
- Predicting vehicle speed moving on the water.
CFD analysis can handle two phase fluid problem with air (gaseous) and water (liquid) interactions with vehicle design, such as ships and amphibious vehicles. CFD analysis can predict the water wave drag on the vechile and water stream around the hull of the vehicle. To predict correct wave drag, water level and water surface need to be predicted very well in the simulation and this analysis is called hydrodynamics. The purpose of the analsis is to optimize hull shape of the vehile to reduce wave drag, to optimize positioning of propellers, to design wave breaker, etc.
Hydrostatic analysis is used to predict the bouyancy force of the water to the vehicle. Initial analysis of any water-vehicle should start with hydrostatic analysis. It will predict necessary volume of wetted part of the vehicle, based on a given vehicle weight. Also, the analysis can predict vehicle attitude while floating on the water, based on a given weight distribution of the vehile. The weight distribution is based on the placement of heavy components, such as engine, transmission, loads, and other supporting components.
