In order to validate the model established in reference [1], a drying experimental study was conducted, and numerical simulation was carried out under the same environmental condition. The experiment and simulation results indicated that the fractal pore network model could explain the drying process of real porous media effectively, the drying curve of fractal models was more consistent with the real drying curve than that of regular models, and its moisture fields well reflected the drying kinetics characteristic of real porous media. There was no correlation between the pore fractal dimension and the drying time, and the simulation result of unsteady-state heat transfer was more consistent with a real drying process than that of steady-state heat transfer for the convective thermal drying.

Abstrak Pohon Marungga merupakan salah satu tumbuhan yang memiliki manfaat yang besar. Untuk daunnya sendiri dapat dijakdikan menjadi suplemen gizi dan juga sebagai bahan dasar kosmetik. Daun Marungga sendiri dapat dijadikan bubuk untuk selanjutnya diproses ke dalam berbagai kebutuhan. Sebelum dijadikan bubuk, sebelumnya daun tersebut harus dikeringkan. Pengeringan manual selama ini membutuhkan waktu yang panjang dan tidak higienis. Pada penelitian ini diperoleh hasil, proses pengeringan selama 19 jam diperolehhasil penurunan kelembaban tidak bisa dilakukan secara cepat. Hal ini disebabkan karena temperatur dalam ruangan tidak mampu memanaskan udara sekitar dengan cepat sehingga proses pengeringan cenderung lebih lambat. Dengan beban pengeringan 20 kg daun Marungga mentah, diperoleh sekitar 3 kg daun kering.Kata kunci: marungga; perpindahan panas; lemari Abstract Marungga tree is one of the plants that have great benefits. The leaves themselves can be transformed into nutritional supplements and also as a cosmetic base ingredient. Marungga leaves themselves can be used as a powder for further processing into various needs. Before being made into powder, the leaf must be dried beforehand. Manual drying so far requires a long time and is not hygienic. In this study the results were obtained, the drying process for19 hours obtained the result of humidity reduction could not be done quickly. This is because the temperature in the room is not able to heat the surrounding air quickly so the drying process tends to be slower. With a drying load of 20 kg of raw Marungga leaves, about 3 kg of dried leaves are obtained.Keywords: marungga; heat transfer; cabinets

Paint Drying

In the automotive manufacturing process, the paint drying process is very important to improve the appearance of the vehicle. In the present study, the fluid flow and heat transfer around a vehicle were numerically investigated for the purpose of predicting the drying performance of the paint drying process. In order to simulate the operating conditions of the paint drying process, the following techniques were used: relative moving boundary conditions, multiple reference frames, and conjugated heat transfer. The present numerical method was verified by comparing the numerical results of the temperature at several monitoring points on a vehicle, while using the experimental data. To evaluate the drying performance quantitatively, the absorbed heat energy that is closely related to the drying of paint was obtained from the numerical simulation. It was found that the drying performance is greatly affected by operating conditions such as the temperature and flow rate of blowing air. To improve the drying performance, the operating conditions of the paint drying process were optimized using the numerical results of various operating conditions.

The drying process can be defined how unit operation for removing water of one moist solid to an unsaturated gaseous phase due to heat transfer. Numerical simulation emerges like a tool that allows the reproduction of drying experiments using computers and suitable softwares. In this sense, this works aims to predict drying process of an industrial hollow ceramic brick inside the kiln using computational fluid dynamics analysis. For one drying temperature of 60°C, results of the drying and heating kinetics, and moisture content, velocity and temperature distributions are shown and analyzed. A comparison between predicted and experimental data of the moisture content and temperature of the brick along the process was done and a good agreement was obtained.
