Coolant in automotive engine cooling systems generally uses coolant with a minimum ethylene2 glycol mixture of 30 percent. Currently. the use of nanoparticles can be mixed in basic coolant between fluid and nanoparticles that have better thermal physical properties than pure coolant. The purpose of this study was to compare the results of CFD to tests on the effect of concentration. https://allfixelectricales.shop/product-category/glass-cleaning-adaptor/
