Performance of annular fins of different shapes subject to locally variable heat transfer coefficient is investigated experimentally in this paper. The performance of the fin expressed in terms of fin efficiency, effectiveness and thermal resistance as a function of the ambient temperature and fin geometry parameters has been presented in the literature in the form of curves known as the fin-efficiency curves for different types of fins without use the diamond shape, but in the present work, we study this shape with others. However, for cases in which the heat transfer from the fin is dominated by natural convection, the …

This is part two of the paper on conceptual design of an engine valve. The previous paper describes the background and the need of an engine valve for an internal combustion engine. The present state of the engine valve technology and the innovations incorporated in its design has been described. This paper presents the conceptualization of an innovative valve train aiming at lesser number of components, reduction in friction and wear, proper sealing, and trimming down pumping losses. Various geometric designs of valve trains have been detailed and compared. Finally a convolution based poppet valve mechanism, which is free from …

Magnetorheological (MR) fluids can be used as brake friction materials [1, 2]. During braking, kinetic energy of machines gets converted into heat and shear thinning of MR fluid due to increase in temperature occurs which in turn reduces the braking effect. To lessen the effect of heat generation on MR fluids due to heat, synthesis of magnetorheological fluid using nano-copper-powder has been proposed. To explore the feasibility of incorporating copper powder, four carbonyl iron (CI) powder based MR fluids (without any copper powder, with 0.25% weight, 0.5% weight and 0.75% weight copper powder) have been synthesized. Yield stress of all …
