  - Rok 2021

  In this paper a prototype of a flow control valve is described and numerically simulated. The flow control valve is used in hydraulic systems to maintain constant fluid flow despite changing loads of a receiver. The standard construction of this type of valves is modified mainly by eliminating the spring. The prototype consists the hydrostatically unloaded throttle valve and pressure ratio valve substituting pressure difference...

  - Rok 2019

  In recent years, the IMO has introduced new regulations to reduce the negative impact of ships on the natural environment. A particularly important step forcing technological innovations is the increasing requirement of ship energy efficiency. It is expressed by the Energy Efficiency Design Index (EEDI). Another important step towards green shipping is rising the required quality of fuel used for propulsion, so called Tier limits....

• Application of advanced CFD simulations in seakeeping analysis of ships (case study)

  Publikacja

  • K. Niklas

  - Rok 2017

  The novel design process of many types of ships needs estimation of seakeeping properties. Especially ships like Offshore Supply Vessels, Wind Farm Support Vessels, Research Vessels, ferries, military vessels, rescue vessels require extended analysis of ship behavior on rough sea. The main reason for improving ships operability in different sea conditions is need of rising efficiency of propulsion system, reducing hull added resistance,...

• Improvement of ships seakeeping performance by application of the full-scale cfd simulations

  Publikacja

  • K. Niklas
  • H. Pruszko

  - Rok 2020

  The ship’s fuel economy is increasingly important. The paper presents the effect of redesigning a case study ship for increasing seakeeping performance. Selected wave parameters reflect very difficult operational conditions existing on the North Sea and the Baltic Sea. The analyzed variants of a case study ship represent the latest developments of modern hull forms. The concepts similar to V-shaped bulbous bow, X-bow, X-aft, B-bow...

  - E3S Web of Conferences - Rok 2018

  The aim of the paper is to evaluate the ampacity of a low-voltage single power cable according to: 1) recommendations of the standard IEC 60287, 2) a Computational Fluid Dynamics method, implemented in Ansys software; and comparison of the results obtained for these two cases. Moreover, limitations of recommendations of the above mentioned standard are indicated.
