An experimental investigation has been conducted to investigate the effect of low-frequency, large-amplitude, horizontal oscillations on convection from a heated horizontal wire (0.008 in. dia) to water and ethylene glycol. Frequencies to 4.5 cps and amplitudes to 2.5 in. were employed. Comparison with a previous investigation has shown that, in the range of this investigation, heat transfer for vertical oscillations is greater than for horizontal oscillations. Comparison of data for water and ethylene glycol showed that previous methods of presenting mixed convection (free plus forced convection) data would not suffice for widely varying fluid properties. A correlating method was developed which successfully correlated the data of this investigation but failed to correlate data of previous investigations. Deficiencies of this method are discussed, and recommendations are given for future correlating methods.
