Studies of thermal conductivity of liquids: Part III

Abstract

Values of thermal conductivity and temperature coefficients for thirty‐five pure organic liquids, in addition to those previously reported, obtained with a previously described apparatus (Part I), are presented. Values of thermal conductivity or temperature coefficients for twenty‐eight of these liquids have not been reported before. The experimentally determined maximum error is ±1.0%. The two methods for predicting the thermal conductivity of liquids previously proposed (Parts I and II) are extended to cover the types of compounds studied in this investigation, in particular ring compounds. The temperature coefficient of thermal conductivity was observed to decrease rapidly, approaching zero as the freezing point is approached. The existence of a transition temperature or region within the liquid state is shown and identified with the onset of molecular rotation.

Review of Thermophysical Property Data of Octadecane for Phase-Change Studies

“…Irby et al [80], Harish et al [81], Wu et al [82], Vélez et al [27], Khadiran et al [83] and Águila V et al [84] applied the transient hot wire (TW) method and Jeon et al [32], Yu et al [38], Motahar et al [85] and Motahar et al [86] used a transient plane source (TP) to measure solid and liquid state thermal conductivities while Ho and Gao [28] have measured the liquid state only with a transient thermal analyser (TA). The stationary methods can be categorized in measurement set-ups analysing the heat flow between parallel plates (SP, stationary plate) [87,88] or coaxial cylinder systems (SC, stationary cylinder) [89,90,91]. Irby et al [80] have achieved some additional results by applying inverse methods (IM) like phase change- and transient conduction experiments.…”
