Intermittent drying is a process in which the and tempering stages are performed sequentially. This has been carried out using different strategies. In this research, goal was focused on calculation of time required for each stage appropriate conditions. order to accomplish such an objective, model established study governing phenomenon by considering all parameters affecting performance process. comprises two submodels, namely, macroscopic microscopic. These submodels coupled other use...
In the present study, several drying experiments were carried out to investigate behavior and feasibility of using intermittent method. Iranian rough rice with initial moisture content (MC) 17.65% (dry basis) was dried by a laboratory-scale dryer an intermediate tempering stage at air temperatures 40°C, 50°C, 60°C velocities 2.2 3.2 m/s. According experimental results, greatly affected performance. Besides, rate increased temperature; however, effect velocity negligible. Various thin-layer...
In this work, several antisymmetric tapered tubes with an inner stiffener under axial and oblique loading are studied optimum dimensions of the tube derived from a crashworthiness point view. The importance detecting these is optimizing weight while not damaged. By using internal stiffener, improved against loads, sensitivity respect to loads bending deformation diminished. numerical models have been developed explicit finite element code LS-DYNA. optimized compared that...
Intermittent drying of paddy rice is fully investigated both theoretically and experimentally. A model developed to describe simultaneous heat mass transfer for the stages tempering ones. The considered cylindrical spherical geometries. excels in considering non-constant air physical properties as well surface vaporization convection. consequent equations are numerically solved with finite-difference method line using implicit Runge–Kutta. Furthermore, a set experiments conducted...
A mathematical model for the Fischer-Tropsch synthesis in a fluidized bed reactor was developed. comprehensive kinetic applied modeling of so that CO conversion correlated with good accuracy over range conditions 523-563K, 0.95-2.55MPa and H2/CO ratio 0.65-1.51. Using model, results showed very agreement experiment. The Average Absolute Deviation percentage (AAD %) 8.98% conversion. In addition, proper product distribution FT process using appropriate has been revealed only 8.09% deviation...
Intermittent drying is a satisfactory technique for of heat sensitive grains especially rough rice. This method consists two separate stages applied intermittently: and tempering. In this work, intermittent rice investigated both theoretically experimentally. order to characterize process; multi-scale model consisting macroscopic microscopic submodels has been developed. Macroscopic calculates the moisture changes bed assuming lumped grains, while submodel determines rate gradient removal...
