Fin Ray Stiffness and Fin Morphology Control Ribbon-Fin-Based Propulsion
Soft Robotics, 2017Ribbon-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, 2004In 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, 2002Fin 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, 2009First 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 ...

Boiling on plate fin and annular fin
International Communications in Heat and Mass Transfer, 1998Abstract 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, 1986Abstract 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 ...
