this paper presents numerical calculations for podded propulsion system using vortex theory and potential panel method. the method discretizes the surface boundary of the body (propeller +pod+strut) and obtained the vortex and propeller surface and potential on strut and pod. a model propeller and strut are considered for these calculations and the results of pressure distribution, flow field a...

this paper describes a contra-rotating propeller (crp) system to calculate the hydrodynamic characteristics and then design the optimum operational condition to be installed on two different large bulk carriers and vlcc. the method is based on boundary element method (bem) to obtain the hydrodynamic performance of any complicated configuration such as crp system, and then the optimum propeller ...

In this paper, a batch hydrogenation reactor performance was modeled using a hydrodynamic and reaction sub-models. The reaction expressions were obtained from the information reported in literature. Experimental studies were conducted in order to generate the experimental data needed to validate the model. The comparison between the experimental data and model predictions seems quite satisfacto...

The traditional method used to estimate the hydrodynamic performance of a ship uses either model test results or one many empirical methods and observe trend in fouling friction coefficient (ΔCF) over time. biggest weakness this is that as well here sometimes not well-fitted for full-scale due several reasons like scale effects and, therefore, may result an inaccurate prediction. Moreover, case...

A desire to further comprehend the hydrodynamic characteristics of three-dimensional undulating fin propulsion is what motivates work. First, a high-resolution numerical technique based on constraint immersed boundary method utilized simulate fluid-fin system. The simulation results reveal fundamental variation laws between performance and kinematic parameters. According data, an in-depth analy...
