Experimental Studies on Thermo-Physical Properties of Nanocellulose–Aqueous Ethylene Glycol Nanofluids

Abstract

Iran ABSTRACT The aim of this experimental research study is to evaluate the thermal behaviour of crystal nanocellulose (CNC) nanofluids. Aqueous ethylene glycol (60: 40; W: EG) used as base fluid and 0.1%, 0.3% and 0.5% volume concentrations were designated here. Crystal nanocellulose nanofluids were prepared by two-step method. Thermal conductivity, viscosity, density, specific heat capacity and pH were assessed with standard measurement method and equipment. In this present work, thermal conductivity of 0.3% CNC nanofluids was increased of about 25% at 80 0 c; viscosity decreased; 0.1% nanofluid exhibit lowest viscosity performance at 80 0 c. In addition to this, 0.5% CNC nanofluid performed better declination of specific heat with increasing temperature up to 70 0 C and lowest error percentage in density measurement. However, some data of the experiments were
