“…First of all hot solution of magnesium sulfate was introduced in the inner tank and heater was started to attained the temperature of 60 o C with constant agitation for few minutes, so that the wall of inner tank attains the constant temperature of hot solution 3 . Then the pump was started to flow the cold fluid through the jacket.…”

“…The previous studies that are related with 3 forced convection flow of wateraluminum oxide (Al 2 O 3 ) and ethylene glycol nanofluids inside a uniformly heated tube subjected to constant and uniform heat flux at the wall. The study concluded that the use of nanoparticles increased the heat transfer at the tube wall considerably for both laminar and turbulent flow.…”

Nanofluids, the fluid suspensions of nanomaterials , have shown many interesting properties, and the distinctive feature offer unprecedented potential for many applications. Nanofluids which are known as new generation of thermal fluids have particular feature which are affected on their behavior. Present paper focuses on behavior of nanofluids in crystallization. The objectives of this paper are to visualize the effect of nanofluid in crystallization operation as compared to convectional fluids i.e water (DW). Results are presented in terms of heat transfer coefficient. For 1% nanofluid heat transfer coefficient is 255.645 w/m 2o K and 264.438 w/m 2o K for 3% nanofluids which enhance significantly the crystallization performance. The use of CuO nanofluids in crystallizer increases the yield of crystallizer. The percentage increase in yield for 1% nanofluids is 4.4% and for 3% nanofluids percentage increase in yield was 5.5%. The nanoparticles used in the experiment was 98.5% pure copper oxide, with an average particle size of 32 nm synthesized by using chemical precipitation method. The nanofluid was prepared by mixing nanoparticles with de-ionized water to prepare experimental concentration of 1% and 3%. The magnesium sulfate solution to be crystallizing is prepared in lab and the average percentage increases heat transfer coefficients for 1% nano-Fluid was found to be 13.1% and 22.31 for 3% nanofluids.

This paper focuses on the nanofluids implementation in the tubular heat exchangers namely, shell and tube, double pipe and coiled tube. The author thinks that a comprehensive review of performed studies in this area can demonstrate advantages and disadvantages of nanofluids application in the heat exchangers. All available papers are reflected in this paper including experimental and numerical studies with all of their important features and findings. The most considered paper confirmed the Nusselt number enhancement with the use of nanofluids in the heat exchangers. Also, nanofluids implementation in the heat exchangers resulted in an increase in the required pumping power, in the most cases.

“…From the heat transfer point of view particularly interesting are two last groups of particles with the emphasis placed on the pure metallic particles. In the literature it was mentioned, that the suspension thermal conductivity even with pretty low particles concentration is much higher than in the case of only base fluid [4]. Numerous experimental studies were carried out in the field of superior thermal properties of the nanofluids compared to typical working fluids used in the heat exchangers.…”

Abstract. The main aim of this paper was to analyze possible utilization of the low concentration nanofluids and the magnetic field to enhance heat transfer. The studied fluids were based on water with an addition of copper particles (40-60 nm diameter). They belonged to the diamagnetic group of materials. As a first attempt to stated target the analysis of enclosure placed in the maximal value of square magnetic induction gradient was carried out. The maximum was in the centre of investigated cavity and it caused the most complex system of gravitational and magnetic buoyancy forces. In the lower part of cavity both forces acted in the same direction, while in the upper part they counteracted. Therefore an enhancement and attenuation of heat transfer could be observed. Due to the particle concentration and magnetic field action the character of flow was changed. In the case of 50 ppm nanofluid the flow was steady end the strong magnetic field didn't change much in its structure except for the suppression of some vortices. In the case of 500 ppm nanofluid the flow was not steady even without magnetic field, but increasing magnetic induction caused change of its structure towards the inertial-convective regime of turbulent flow.
