     this work compares experimentally the effectiveness of substituting the water-based suspensions of al2o3 nanoparticles (nanofluid) and of micro-encapsulated phase change material particles (pcm suspension) for the pure water for laminar forced convective cooling through an iso-flux heated circular horizontal tube. convection heat transfer experiments have been undertaken for the tube using the pure water, the pcm suspensions (ωpcm = 2, 5, and 10 wt.%) and the nanofluids (ωnp = 2, 6, and 10 wt.%) as the working fluids under the following operating conditions: the volume flow rate q = 25–240 cm3/min (the reynolds number ref = 195–1801), the heating power applied at the outer wall of the tube qo = 20, 30, 40 w, and the inlet fluid temperature tin = 32.8–33.2 °c. in addition, a scale analysis together with integral energy balance is presented concerning thermally developing heat transfer characteristics of the water-based suspension flow in the tube. the convective cooling performance of the water-based suspensions was gauged in terms of local and surface-averaged temperature control effectiveness along the tube wall compared with that obtained for the pure water. furthermore, the water-based suspensions were compared based on the figures of merit for their heat transfer performances against the corresponding pressure drop penalty.
