This book was released on 1982 with total page 39 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report consists of an experimental evaluation of tunnel hull configurations on a planing hull model and determination of the optimum longitudinal placement of the propeller in an existing tunnel design. Resistance, self-propulsion, and draft data are presented for Model 5048 fitted with twin tunnels which have a depth of 40 percent of the tunnel diameter. Effects of propeller tip clearance and nozzle sideplates installed in the tunnels were also investigated. The longitudinal placement of the propeller inside the tunnel had a small effect on powering and draft with the forward location having slightly less delivered power than the aft locations. The addition of nozzle sideplates significantly reduced the draft, running trim and propulsive coefficient at high speeds. However, the nozzle sideplates significantly increased the resistance and delivered power. (Author).

Book excerpt: Marine Design XIII collects the contributions to the 13th International Marine Design Conference (IMDC 2018, Espoo, Finland, 10-14 June 2018). The aim of this IMDC series of conferences is to promote all aspects of marine design as an engineering discipline. The focus is on key design challenges and opportunities in the area of current maritime technologies and markets, with special emphasis on: • Challenges in merging ship design and marine applications of experience-based industrial design • Digitalisation as technological enabler for stronger link between efficient design, operations and maintenance in future • Emerging technologies and their impact on future designs • Cruise ship and icebreaker designs including fleet compositions to meet new market demands To reflect on the conference focus, Marine Design XIII covers the following research topic series: •State of art ship design principles - education, design methodology, structural design, hydrodynamic design; •Cutting edge ship designs and operations - ship concept design, risk and safety, arctic design, autonomous ships; •Energy efficiency and propulsions - energy efficiency, hull form design, propulsion equipment design; •Wider marine designs and practices - navy ships, offshore and wind farms and production. Marine Design XIII contains 2 state-of-the-art reports on design methodologies and cruise ships design, and 4 keynote papers on new directions for vessel design practices and tools, digital maritime traffic, naval ship designs, and new tanker design for arctic. Marine Design XIII will be of interest to academics and professionals in maritime technologies and marine design.

Available in PDF, EPUB and Kindle. Book excerpt: Wind tunnel tests were conducted on a shrouded propeller model in which the propeller diameter was varied for the purpose of measuring the effects of tip to shroud clearance. The basic model tested contained a four-bladed variable pitch propeller operating within a 0.50 chord/diameter ratio shroud. To assist in studying the effect of annulus area on tip clearance, two models having 0.30 and 0.40 hub/tip diameter ratio centerbodies were tested over roughly the same range of propeller tip clearances. Performance of the models was measured throughout a range of advance ratios from zero to roughly 2.20 at several propeller blade pitch settings at zero angle of attack only. Results are presented in the form of force and power coefficients and efficiency varying with propeller tip clearance and rotational speed for forward and static flight conditions. (Author).

This book was released on 1998 with total page 1110 pages. Available in PDF, EPUB and Kindle. Book excerpt: These proceedings contain the papers presented at the 7th International Symposium on Practical Design of Ships and Mobile Units. The symposium was held at the Congress Centre in The Hague, The Netherlands on 20-25 September, 1998.The overall aim of PRADS conferences is to advance the design of ships and mobile marine structures through the exchange of knowledge and the promotion of discussions on relevant topics in the fields of naval architecture and marine and offshore engineering. Greater international co-operation of this kind can help improve design and production methods and so increase the efficiency, economy and safety of ships and mobile units. The main themes of this symposium are design synthesis, production, ship hydromechanics, ship structures and materials and offshore engineering. Some topics which attracted many papers were design loads, design for ultimate strength, impact of safety and environment, grounding and collision, resistance and flow, seakeeping, fatigue considerations and propulsor and propulsion systems.
