Estimation of Heat Transfer Rate with Conjugate Gradient Method
Abstract: In thermal system, a considerable amount of heat leftovers with the exhaust flue gases. Appropriate arrangement to recover this waste heat may contribute to the enhancement of overall utilization of the energy supplied to the thermal system. In this study, heat transfer rate is approximately determined using inverse heat transfer concept. Simulated temperature readings have been taken at the measurement location on the mild steel rod. Conjugate gradient method (CGM) …

Investigation of Physical Characteristics and Machining Parameters of Improved Al-SiC MMC Using Dry EDM Process for Aerospace Industries
Abstract: Aluminium-based composite is widely used in aerospace and automobile industries because it is lighter in weight; but the trouble is that it is easily worn-out and life of the components is decreased. To overcome these problems, aluminium silicon carbide composite material has been developed with good wear-resistance, hardness and lighter weight. Silicon carbide has good mechanical properties like wear resistance, hardness, toughness and high melting point. Silicon carbide weight fractions …

An Application of PARETO Chart for Investigation of Defects in FNB Casting Process
Abstract: Casting is one of the widely used manufacturing processes consisting of melting and pouring the metal into the mould to get the desired shape. Furan no-bake system is a binder system consisting of furan resin and acid catalyst. It is a fast growing system due to its excellent surface finish and dimensional accuracy. Although having high dimensional accuracy, many defects arise in FNB casting such as sand inclusion, gas porosity, …

Experimental Investigation of Surface Modification on Copper (Cu) with Pen-Shaped Plasma Torch
Abstract: The paper presents an experimental investigation on surface modification of copper (Cu) material by plasma treatment using pen-shaped plasma torch. Plasma is used for a variety of industrial applications like surface modifications, surface activation, and surface treatment for coating technology. The plasma device construction here is simple and effective. This development was required because available device is not useful for practical applications due to limited effective surface treating area. In …

Investigation of Heat Transfer in Concentric Annuli with Perforated Inserts
Abstract: The increasing necessity for saving energy and material imposed by the diminishing world resources and environmental concerns have prompted the development of more effective heat-transfer equipment with improved heat-transfer rates. The hydrodynamic boundary layer acts as main resistance for the transfer of heat from tube surface to fluid or vice-versa and many researchers are trying to improve the convective heat transfer rate with inserts in tubes to break the boundary …

Numerical Modeling of Elastoviscoplastic Material Model in Strain Space
Abstract: Conventional material non-linear analysis works with stress-space plasticity. It uses yield function, loading-unloading criteria, and flow rule in terms of stress parameters. It shows ambiguity in loading-unloading criteria for softening materials. During such situations, an alternative strain-space formulation becomes quite useful to carry out analysis of such materials. The viscoplastic response of materials requires the time integration of system of non-linear first order differential equations. In viscoplasiticy, the constitutive equation …
