Abstract
Salah satu fasa air setelah uap jenuh adalah fasa uap superheat dimana temperaturnya kurang lebih 100oC. Secara eksperimen telah dikembangkan suatu pembangkit uap superheat yang mudah dibawa (portable) dimana dengan menggunakan ketel yang sudah ada di pasaran kemudian dilakukan modifikasi penambahan sirip di sepanjang dinding ketel. Temperatur uap yang dihasilkan dapat mencapai 200-an derajat celcius. Namun untuk pengembangan lebih lanjut metode eksperimen langsung akan menghabiskan dana yang cukup besar, oleh karena itu akan dilakukan pemodelan dengan menggunakan software. Dengan memanfaatkan bantuan komputasi komputer untuk melakukan perhitungan. Pada umumnya terdapat tiga tahapan untuk melakukan proses simulasi, yaitu: preprocessing, processing dan postprocessing. Berdasarkan pengukuran, uap superheat yang dibangkitkan yaitu sekitar 250.C. Temperatur uap superheat yang dihasilkan alat dengan temperatur yang dihasilkan simulasi tidak jauh berbeda. Temperatur yang dihasilkan simulasi sebesar 227oC. Penggunaan sirip menunjukkan bahwa ketercapaian temperatur uap superheat dipengaruhi oleh laju aliran kalor.

One of the water phase after the saturated vapor is the vapor phase in which the superheat temperature of approximately 100°C. In experiments have developed a superheat steam generators, portable which by using a kettle that is already on the market than modification of adding fins along the walls of the boiler. The resulting steam temperature can reach 200 degrees Celsius. However, for the further development of the direct experimental method would spend substantial funds, therefore, will do the modeling by using software. By utilizing the help of computational computer to perform calculations. In general, there are three stages to perform process simulation, namely: preprocessing, processing and postprocessing. Based on the measurements, the superheat steam is generated which is about 250⁰C. Superheat steam temperature generated by the temperature generated tool simulation is not much different. The resulting simulation temperature of 227oC. The use of fin indicates that the achievement of superheat steam temperature is influenced by the rate of heat flow.
