Analisis Oistribusi Suhu, Aliran Uoara Dan Rh Oalam In-Store Dryer (Iso) Untuk Biji-Bijian Menggunakan Computational Fluid Dynamics (Cfo)

Abstract

In-Store Dryer (ISD) consist of dryer and storage system, it is commonly used as second step in drying process of grains. ISD is usually utilized ambient temperature. Temperature, air flow and RH are key parameters during drying process using ISD. The objective of this study were to analyze the distribution of temperature, air flow, RH inside ISD. Computational Fluid Dynamic (CFD) was used to analyze the distribution of temperature, air flow and RH inside ISO. The dimensions of ISD was 3.5 m in high and 2.5 m in diameter. ISD have 13 aeration pipes of air flow, consist of 9 input pipes and 4 output pipes. All walls of ISD were assumed to be in condition of adiabatic. The result showed that CFD simulation of temperature, air flow and RH have coefficient of correlation of 0.66; 0.73; and 0.66 respectively. Base on the CFD analysis, utilizing of the porous pipes isoetter than half porous pipes in the ISD.
