Modifikasi Solar Water Destiler Dengan Menambahkan Unit Pemanas Berenergi Solar Cell

Increasing the heat energy in the evaporator box from the Water Solar Destiler, by adding a wire heater aims to increase the heat energy in the evaporator box so that it will speed up the evaporation process in the evaporator box. The more liquid that is broken down due to heat energy into water vapor, the more discharge will be produced. Based on the results of the observations made, the addition of a wire heater in the evaporator city with AC electricity generated by solar panels, increased the purified water by 248.78%, from 1745 ml to 4341 ml, with the thickness of the water being purified as thick as 1 cm which was dried in the sun. for 10 hours starting from 07.00 WIB to 17.00 WIB.

Bubble Dynamics During Boiling in Polydimethylsiloxane (PDMS) Microchannels With Wire Heater

Boiling is an important phase-change mode with efficient heat transfer and complex bubble dynamics. A microchannel fabricated using Polydimethylsiloxane (PDMS), which is a porous polymer, performed different boiling behavior and heat transfer compared to traditional glass or silica microchannels. A very fine platinum wire embedded in the PDMS microchannel served as a heater. Bubble dynamics was visualized and recorded through a high speed CCD camera equipped in a microscope. Boiling curves were concluded, and different boiling regimes were classified. The featured phenomena of droplets cycle in big bubbles were observed and analyzed.
