This research demonstrates how to develop a novel energy balance equation investigate heat transmission between the components of bifacial photovoltaic-thermal (PVT) air heater with jet plate. The temperature output and efficiency system are shown. A greater mass flow rate reduces exit increases thermal component. Increased sun irradiation raises efficiency. In terms electrical efficiency, PV p...

The 3ω method for measurement of thermal conductivity of a solid usually consists of a strip heater above a substrate, and the method is based on an approximate solution of the heat conduction problem in which the heater thickness is neglected. We establish a two-dimensional heat conduction model for the heater-on-substrate 3ω method which takes into account the finite thickness of the heater. ...

Güneş destekli hava ısıtıcıların çok yaygın kullanım ile birlikte ısı transferi verimlerinin düşük olduğu bilinmektedir. Bu konuda çeşitli çalışmalar yürütülmektedir. Yapılan bu çalışmada yutucu plaka üzerine kare kesit yapay pürüzlülük oluşturularak tasarlanan bir güneş ısıtıcısının sayısal analizi yapılmıştır. Kütle, momentum ve enerji korunumu denklemlerinin simülasyonu, kullanılan hesaplama...

Fish as a source of animal protein is fishery commodity that prone to quality deterioration and spoilage after the fish caught, so it needs fast, precise correct handling keep its in hands consumers. There for necessary have process extends durability through drying. One drying alternative use Solar Air Heater with an Ultra Violet (UV) Dryer house by making building made transparent material fu...

Prinsip kerja industri pembangkit listrik tenaga uap secara umum adalah pembakaran batu bara pada boiler untuk memanaskan air dan mengubah menjadi panas (superheated steam). Uap tersebut digunakan menggerakkan turbin menghasilkan dari kumparan medan magnet di generator. Heater salah satu alat penukar kalor yang banyak berfungsi 
 sebagai pemanas umpan sebelum masuk ke boiler. Pada Jawa Tim...
