Abstract

Background/Objectives: To find the best method for nanofluid stability or increment in heat transfer enhancement and terminating pressure drop. Methods/Statistical analysis: Nanofluids have big problem regarding its own preparation or stability. Here is details which can prevent both of problem. This paper based on a work which is able to prevent nanofluids stability problem or pressure drop problem in MCHS. Findings: MCHS vary from 2 cm to several feet or meter because its depends on the requirement of work. The design procedure is complex because of its diameter vary in micro-meter, but it can be designed for our requirement easily. Traditionally we utilized water, ethylene-glycol & some special kind of oils. But, with the large demand in obligation of working efficiency nanofluids were produced which are colloidal mixture of base fluid with nanoparticles. Nanofluids have truly developed the heat transfer characteristics of base fluids & hence are great base to overall working efficiency of the system. But along with advantages it also has quite a few disadvantages to which are stability, limitation to the volumetric concentration addition process of manufacturing and most of all economics of production. Improvements/Applications: They can also be used for wide range of applications such as in the chemical industry, food processing industry, refrigeration industry, computer technology industry, automobile industry, aerospace industry, power plant, mechanical industry etc.
