“…Drop test experiment is very important in heat and mass transfer study. For decades, it has been used to enhance the understanding regarding the nucleate boiling [1]- [2], transition boiling [3]- [5] and film boiling [6]- [8] process. This technique was used to study the boiling process and evaporation characteristic of droplet during impact on solid surfaces whether when being heated or in room temperature.…”

The main objective of this paper is to conduct a manual drop test experiment to investigate the actual size and volume of a single droplet. Both experimental result and theoretical value were calculated for comparison. In this study methanol was chosen as the test liquid. The drop test was repeated numerous times with the droplet size measurement being calculated for every 50, 100 and 150 drops. A digital weight measurement was used to precisely measure the droplet weight in the drop test. Meanwhile for theoretical calculation, measurement was made based on chemical properties of the liquid itself. Based on the comparison, it was found that the experimental measurement of droplet size and volume is comparable with the theoretical calculation.

In the Tempcore process, reinforcing bars are produced by short and intensive cooling. This rapid quenching converts the surface layer of a steel bar to a hardened structure. The exact simulation of the Tempcore process by a thermomechanical system is difficult to achieve because its cooling capacity is generally not sufficient to follow the Tempcore cooling rate. Therefore, herein, a hollow specimen is designed to increase the cooling rate. A series of thermomechanical tests following predetermined cooling curves provided by the thermal model is performed. The measured hardness of the thermomechanical‐tested specimen is used to predict the tensile strength of a Tempcore rebar based on the rule of mixture. The results show that the prediction of the strength of a Tempcore rebar by tailored cooling with a hollow cylindrical specimen is feasible with a high degree of reliability.
