EXPERIMENTAL ANALYSIS OF ENHANCED PERFORMANCE OF PLATED HEAT EXCHANGER USING IN MILK PASTEURATION PROCESS BY USING NANO FLUID

Abstract

Experimentally to analyzed the enhance performance of Plate heat exchanger in milk pasteurization process
using nanofluid at different concentration of 0.1%,0.15%,0.2% 0.25% and 0.3%. in this work the nanoparticles like Al2O3
and the base fluid like dematerialized water is used to prepare nanofluid by using two steps method. Exchanger is one of the
thermal energy transferring devices, which transfer the heat between different fluids. This is widely used in different
application because of its compact in size and higher efficiency compared to other type of heat exchanger. The main focus of
using nanofluid is that it has improvement in thermal conductivity. Than the hot fluid as milk and cold fluid as nanofluids are
used. The heat transfer rate is increased with increasing the concentration of nanofluid. It conducted by varying operating
parameters like mass flow rate of hot milk, mass flow rate of nanofluid , inlet and outlet temperatures of hot milk and inlet
outlet temperature of nanofluid . The main objective of this work is to find out mass flow rate and overall all heat transfer
coefficient.
