Experimental investigation of critical heat flux during impact of a droplet onto hot horizontal surface
The purpose of this research is to investigate the Critical Heat Flux (CHF) and its relationship with thermal inertia during impact of a droplet on hot horizontal surface. In the study, three (3) different types of material were used which were Aluminum, Brass and Stainless Steel (304). The mate...

| description | The purpose of this research is to investigate the Critical Heat
Flux (CHF) and its relationship with thermal inertia during
impact of a droplet on hot horizontal surface. In the study,
three (3) different types of material were used which were
Aluminum, Brass and Stainless Steel (304). The materials
dimension were 50.0 mm in diameter and 30.0 mm in height.
The materials were polished until they became a mirror
polished surface. Ethanol was used as the test liquid. The
droplet diameter was approximately 3.528 mm. The impact
height was approximately 65.0 mm corresponding to impact
velocity of 1.129 m/s. The evaporation lifetime was measured
in seconds by using a digital stopwatch. As a result, it was
observed that the CHF occurred at the surface temperatures of
105, 120 and 160 °C for aluminum, brass and stainless steel,
respectively. It was also observed that all CHF data showed an
evaporation lifetime below 1 sec order which is similar with
other literatures. |
