Abstract


Compact heat exchangers are widely used in various applications in thermal fluid systems.
The traditional approach of increasing the total heat transfer rate by using fins & micro
channel has already reached to their limit. Hence there is a need for new & innovative heat
transfer fluids for improving heat transfer called nano-fluid. This work presents a detailed
numerical investigation on compact heat exchanger by using different nano-particles in base
fluid 90% water-10% EG as a coolant for straight fin geometry. For the numerical
investigation computer codes are developed in MATLAB language.
A theoretical analysis is presented to investigate the thermal performance of a compact heat
exchanger by using SiO2,TiO2&ZnOnano particles in mixture of 90% water & 10% EG.
Different correlations are used based on the experimental work on the same group of nano
fluid.
