Fin Ray Stiffness and Fin Morphology Control Ribbon-Fin-Based Propulsion

Soft Robotics, 2017
Ribbon-fin-based propulsion has rich locomotor capabilities that can enhance the mobility and performance of underwater vehicles navigating in complex environments. Bony fishes using this type of propulsion send one or multiple traveling waves along an elongated fin with the actuation of highly flexible rays that are interconnected by an elastic ...

On The Optimization of Circular Radiating Fins With Fin to Fin and Fin to Base Radiant Interaction

Journal of Heat Transfer, 2004
In the present study the optimum dimensions of circular rectangular and triangular profile fins with fin-to-fin and fin-to-base radiant interaction are determined. The basic assumptions are one-dimensional heat conduction and black surface radiation. The governing equations are formulated by means of dimensionless variables and solved numerically.

Fin Efficiency of Serrated Fins

Heat Transfer Engineering, 2002
Fin efficiency of serrated fins was analyzed and an analytical solution of the theoretical fin efficiency was derived in the form of a function of modified Bessel functions. Furthermore, an approximate equation has been given which enables one to calculate the theoretical fin efficiency with a pocket calculator with an accuracy of - 1.5%.

FIRST INTEGRALS OF FIN EQUATIONS FOR STRAIGHT FINS

Modern Physics Letters B, 2009
First integrals admitted by second-order nonlinear ordinary differential equations modeling the temperature distribution in a straight fin are obtained. After imposing the boundary conditions these first integrals give a relationship between temperature at the fin tip and the temperature gradient at the base of the fin in terms of the fin parameters ...

„Fin de siècle – fin de sexe“

2021
Anne-Berenike Rothstein beschäftigt sich in ihrem Beitrag mit der »reine des décadents« Rachilde (1860-1953), weiblicher Dandy, selbsternannter »Homme de lettres« und Crossdresser im männlich dominierten Literaturdiskurs des fin de siècle. Anhand ihrer berühmtesten Romane (Monsieur Vénus, 1884, und Madame Adonis, 1888) konzentriert sich die Analyse auf

Boiling on plate fin and annular fin

International Communications in Heat and Mass Transfer, 1998
Abstract This paper for the first time theoretically investigated the heat transfer performance and associated stability characteristics of a plate fin or an annular fin subject to boiling. Stability analysis reveals that in both cases, the N, F, TN and FTN modes are stable; while in the T or FT modes, the operation remains stable only if the fin ...

Calculation of fin efficiency for condensing fins

International Journal of Heat and Fluid Flow, 1986
Abstract The use of condensing fins is commonplace in heat exchange applications. In calculating the fin efficiency, the heat transfer coupling between the condensate boundary layer and heat conduction in the fin has to be accounted for. This involves the simultaneous solution of the fin equation and the condensate layer equations, and therefore ...
