Reply to ''Comments on 'Efficiency of the solid-state engine made with Nitinol memory material' ''

Journal Article Golestaneh, A A - J. Appl. Phys.; (United States)

In reply to the comments of Mohamed and Banks, we outline the conditions under which a Ni-Ti shape-memory element operates in a solid-state engine. The expression for the energy output of this element, which was used in the original paper, is derived here, and further aspects of the efficiency formula for this engine are explained.

Comments on ''Efficiency of the solid-state engine made with Nitinol memory material''

Journal Article Mohamed, H A ; Banks, R M - J. Appl. Phys.; (United States)

A recent calculation of the thermal efficiency of a solid-state engine made with a Ni-Ti alloy (Nitinol) has been criticized with reference to the origin of the work output and the deformation behavior of the material.

Efficiency of the solid-state engine made with Nitinol memory material

Journal Article Golestaneh, A A - J. Appl. Phys.; (United States)

The thermal efficiency of the solid-state engine (SSE) based on the shape-recovery phenomenon accompanied by the martensite-parent-phase (M..-->..P) transformation has been evaluated. Particular application is made for the memory components made with the Nitinol alloys. The result is expressed in terms of the hot and cold reservoir temperatures (T and T/sub 0/), the latent heat of the M..-->..P transformation, ..delta..H, the fraction of the M..-->..P transformation, ..cap alpha.., and a coefficient ..beta.. that depends on the geometry and type of the deformation of the memory component. The relationship between the efficiencies of the SS and the Carnot engines is discussed.more »« less

Solid state engine using Nitinol memory alloy

Patent Golestaneh, A A

A device for converting heat energy to mechanical energy includes a reservoir of a hot fluid and a rotor assembly mounted thereabove so a portion of it dips into the hot fluid. The rotor assembly may include a shaft having four spokes extending radially outwardly therefrom at right angles to each other, a floating ring and four flexible elements composed of a thermal memory material having a critical temperature between the temperature of the hot fluid and that of the ambient atmosphere extending between the ends of the spokes and the floating ring. Preferably, the flexible elements are attached tomore »« less
