In this study, heat transfer characteristics of Tetra-n-butyl ammonium bromide (TBAB) hydrate slurry in horizontal tube were investigated experimentally. The coefficient of heat transfer was measured. The initial concentrations, solid fraction, inner diameter of pipe and Reynolds number were varied as the parameters. In the laminar flow condition, the coefficient of heat transfer increased with an increase in the solid fraction. However, in the turbulent flow condition, the coefficient of heat transfer was similar to the values without solid phase in low solid fraction. In addition, the results of measurement were arranged using the non-dimensional number such as the Nusselt number.
