摘要: Abstract Measurements of quasi-static advancing contact angles refrigerant R134a on copper and aluminum surfaces are reported over a temperature range from 0 °C to 80 °C. The metal tested were (alloy 3003) 101) plates. done using direct optical observation technique where the liquid meniscus at surface vertical plate was captured high magnification camera system. angle solid–liquid interface deduced by enhancing manipulating digital image solid modeling software drawing tangent line intersection location solid, vapor. Values found vary between 8.3° 5.6° for 5.1° 6.5° when rose Maximum standard deviation amongst measured values 1.3°.
