Drying of Matricaria recutita flower was investigated experimentally in a VibroFluidized Bed Dryer (VFBD). The aim of the present work was to optimize the best operating conditions for the drying of Matricaria recutita flower in the VFBD based on experimental design techniques. Response Surface Methodology (RSM) and Central Composite Design (CCD) based on 4-variable with 5-level have been e...
Use of renewable energy resources might be the solution for electric power shortage in agricultural production. Wind turbines used places with higher wind potential, such as coastline Marmara Sea and Tekirdağ Province. Generally, natural ventilation greenhouses is insufficient. Mechanical must order to improve achieve desired levels. However, are generally located on rural areas mechanical cann...
cooling towers are widely used in most industrial units to reject waste heat to the atmosphere. this paper deals with an experimental analysis of heat and mass transfer phenomena between water and air by direct contact in a cooling tower. the tower is filled with 6 type packing. in this study temperature and pressure drop and tower characteristics was used in determining experimentally the ther...
The difficulties in the storage of fruit juice and the use of juice powder in various food processing industries has made the juice powder attractive to consumers and producers. Making powder from fruit juice is one of the most complex methods of fruit processing.The hygroscopic nature of fruit juice component and its thermoplastic properties has caused the drying time control and the transport...

run-out-table (rot) is located between last finishing stand and down coiler in a hot strip mill. as the hot steel strip passes from rot, water jets impact on it from top and bottom and strip temperature decreases approximately from 800-950 °c to 500-750°c. the temperature history that strip experience while passing through rot affects significantly the metallurgical and mechanical properties, s...
In this paper double flow packed bed solar air heater has been investigated theoretically. The effect of air mass flow rate, porosity and different depth ratios at study state conditions on the thermal performance of a double flow packed bed solar air heater is found by using the alternative simulation system. Comparisons between the measured thermal and effective thermal efficiency of the doub...
thermal modeling of an automotive cabin was performed in this paper to predict the inside cabin air temperature. to implement this task, thermal and ventilation loads were estimated and the mass and energy balance conservation equations for dry air and water vapor with considering a new parameter (air circulation ratio) as well as the balance equations of internal components of a cabin were der...
Introduction Hundreds of millions of patients are affected by nosocomial infections worldwide each year, leading to significant mortality and financial losses for health systems. Maintenance of adequate indoor air quality Air (IAQ) at hospitals is critical to the prevention of these infections. Evaluation of IAQ can be performed by bioaerosol sampling and particle counting. The current study a...
In this article, turbulent flow heat transfer in the air gap between rotor and stator of a generator under nonhomogeneous heat flux is studied experimentally. The rotor consists of four symmetrical triangular grooves. The stator surface is smooth and does not include any grooves. The relative heat flux between the rotor and the stator is 1 to 3. Temperature and heat flux are measured locally at...
