Analysis and Experiments for Contra - Rotating Propeller
Contra-rotating propellers have renewed interest from the naval architecture community, because of the recent development of electric propulsion drives and podded propulsors. Contrarotating propulsion systems have the hydrodynamic advantages of recovering part of the slipstream rotational energy which would otherwise be lost utilizing a conventional screw propeller system. The application of th...
متن کاملOn fans in multigraphs
We introduce a unifying framework for studying edge-colouring problems on multigraphs. This is defined in terms of a rooted directed multigraph F which is naturally associated to the set of fans based at a given vertex u in a multigraph G. We call F the “Fan Digraph”. We show that fans in G based at u are in one-to-one correspondence with directed trails in F starting at the root of F . We stat...
متن کاملFluid-structure interaction studies on marine propeller
Composite propellers offer high damping characteristics and corrosion resistance when compared with metal propellers. But the design of a hybrid composite propeller with the same strength of metal propeller is the critical task. For this purpose, the present paper focusses on fluid-structure interaction analysis of hybrid composite propeller with Carbon/Epoxy, R-Glass/Epoxy and S2-Glass/Epoxy t...
متن کاملLarge alluvial fans on Mars
[1] Several dozen distinct alluvial fans, 10 to 40 km long downslope, have been observed in highlands craters. Within a search region between 0 and 30 S, alluvial fan-containing craters were found only between 18 and 29 S, and they all occur at around ±1 km of the MOLA-defined Martian datum. Within the study area they are not randomly distributed but instead form three distinct clusters. Fans t...
متن کاملA Note on Ramsey Numbers for Fans
For two given graphs G1 and G2, the Ramsey number R(G1,G2) is the smallest integer N such that, for any graph G of order N, either G contains G1 as a subgraph or the complement of G contains G2 as a subgraph. A fan Fl is l triangles sharing exactly one vertex. In this note, it is shown that R(Fn, Fm) = 4n + 1 for n ≥ max{m2 − m/2, 11m/2 − 4}. 2010 Mathematics subject classification: primary 05D...
