Since a decade ago, investigation on nanofluids has grown significantly owing to its enhanced thermal properties compared conventional heat transfer fluids. This engineered nanofluid been widely used in the engineering system improve their energy consumption by improving efficiency of system. The addition nano-size particles as additives dispersed base fluids proved either or diminish behaviour...

Theoretical analysis and Computer simulations have proven to be cost-effective and powerful tools in scientific studies of materials, particularly at nano-scale where synthesis of nano-structures, interpretation of their observed character and exploration of new structures are not always straight forward. We present here fundamental principles of techniques used today for computational simulati...

This numerical analysis aims to observe and analyze the combined convection characteristics of micropolar tri-hybrid nano-liquid that moves around a cylindrical object, and, in addition, compare its thermal behavior hybrid mono nano-fluids. For this purpose, problem is modeled by developing Tiwari Das models, then governing model converted into dimensionless expressions, finally, solved using K...

Two simple optofluidic devices based on a microprism and a refraction channel, respectively, are proposed for measuring the refractive index of fluids. The microprism chip consists of an optical waveguide channel and a single triangular chamber filled with the test fluid, while the refraction channel chip consists of a single turning channel which functions as a liquid-core/solid-cladding optic...

The cooling system of an Automobile plays an important role in its performance, consists of two main parts, known as radiator and fan. Improving thermal efficiency of engine leads to increase the engine's performance, decline the fuel consumption and decrease the pollution emissions. Water and ethylene glycol as conventional coolants have been widely used in radiators of an automotive industry ...

The most important reason for the design of curved tubes is increasing the heat transfer between the fluid and the wall which has provided many applications in various industries such as air conditioning, micro-electric, heat exchangers and etc. The aim of this study is numerical investigation of nano fluids flow in spiral tubes with injection of base fluid in different Reynolds numbers. Accord...

It is seen that the development of microfluidic laboratories working passively on chips has increased over years. The field microfluidics includes use microstructured devices, which typically have micrometer sizes and allow precise processing low volumes. Nano fields are main nanotechnology, science such as earth science, organic chemistry, molecular biology, semiconductor physics, micromachine...
