In this work a mathematical model is developed for measuring orientation of red blood cells in magnetic field and governing the bio-magnetic fluid flow is presented for the viscous, two-dimensional, incompressible and laminar time dependent heat transfer flow is considered. Expressions describing the variation of the saturation magnetization of the fluid with temperature or the magnetic field i...

Continued emphasis on development of thermal cooling systems is being placed that can cycle low grade heat. Examples include solar powered unmanned aerial vehicles (UAVs) and data storage servers. The power efficiency of solar module degrades at elevated temperature, thereby, necessitating the need for heat extraction system. Similarly, data centres in wireless computing system are facing incre...

Magnetic shape memory alloys display magnetic-field-induced strain (MFIS) of up to 10% as single crystals. Polycrystalline materials are much easier to create but display a near-zero MFIS because twinning of neighboring grains introduces strain incompatibility, leading to high internal stresses. Pores reduce these incompatibilities between grains and thus increase the MFIS of polycrystalline Ni...

This paper describes a physics-of-failure (PoF) based prognostic method for power electronics modules (PEMs). Differing from the traditional reliability prediction methods, this approach allows the reliability performance of PEMs to be assessed in real time. Four techniques have been used to develop this method, they are: (1) Compact electro-thermal model (2) Rainflow counting algorithm (3) Com...

The defect in work rolls directly influence the forming cost and the final shape of the product. The researchers tend to investigate the thermo-mechanical stress in work roll of rolling machines. These stresses may reduce the roll life. Since the investigation of the thermo-mechanical stress in work roll with real-conditions is complex, comprehensive studies by means of numerical methods are av...
