Abstract

Sunulan çalışmada, sayısal yöntemler kullanılarak h-BN/DCM ve SiO2/DCM nanoakışkanlarının akış karakteristikleri ve basınç düşüleri, farklı boru çaplarında incelenmiştir. Kullanılan boru çapları 0,0127 m, 0,0254 m, 0,0381 m, 0,0508 m ve 0,0762 m’dir. Nanoakışkanların hazırlanmasında dikolorometan (DCM) baz akışkan olarak kullanılmış, ve heksagonal bor nitrür ve silika, baz akışkana %1 oranında karıştırılmıştır. Her ne kadar nanoakışkanlar günümüzde birçok termal ve termodinamik analize konu olmuş olsa da, baz akışkana kıyasla viskozitelerindeki artışın sebep olduğu enerji kayıpları ile ilgili araştırmalar yetersiz kalmıştır. Bu çalışma sonucunda da sabit boru çapında basınç düşümünün en yüksek 0,00056 kg/ms ile en yüksek viskoziteye sahip SiO2/DCM nanoakışkanında, en düşük basınç düşümünün de en düşük viskoziteye sahip DCM’de olduğu görülmüştür.

The Investigation of Flow Characteristics and Pressure Drops of h-BN/DCM and SiO2 Nanofluids

Year 2022, Volume: 25 Issue: 1, 427 - 434, 01.03.2022

Abstract

The present study is about the investigation of the flow characteristics and pressure heads of h-BN & DCM and SiO2 & DCM nanofluids at various pipe diameters by using numerical methods. The pipe diameters are 0.0127 m, 0.0254 m, 0.0381 m, 0.0508 m, 0.0762 m. Dichloromethane (DCM) was used as base fluid in nanofluid preparation. Hexagonal boron nitride and silica were mixed into the base fluid by 1% when obtaining the nanofluids. Although nanofluids have been located in the center of many thermal and thermodynamic analyses, the scientific research about the energy losses caused by their increased viscosity compared to the base fluids have remained insufficient. This study investigates the pressure losses of several nanofluids and their behaviors in a pipe. It was found out that the highest increment in pressure drop was in SiO2-DCM which has the largest viscosity of 0.00056 kg/ms and the smallest increment in pressure drop is in DCM which has the lowest viscosity with 0.000413 kg/ms for a constant pipe diameter.
