The research investigates the convective heat transfer by means of Thermochromic Liquid Crystals and velocity flow field using 3-D Stereo-PIV (Particle Image Velocimetry) The application of a swirl cooling flow technique in combination with convective heat transfer measurements at three different Reynolds numbers 7 000 14 000 and 21 000 of the mass transfer in drying of shrinking particles in this study shrinkage and drying characteristics of moringa seeds exposed to infrared (IR) radiation were experimentally determined The IR source was located at a distance of 18 cm from the samples Experiments were conducted with the seeds

Effect of mass on convective heat transfer coefficient

In this work an attempt is made to study the effect of mass on convective heat transfer coefficient (CHTC) for open sun drying (OSD) of groundnut (Arachis hypogaea L ) Experiments were conducted during the month of May 2016 in the climatic condition of Rohtak India (2854′0″N 7634′0″E)

In this research energy and exergy analyses of drying characteristics quality and mass transfer parameters for microwave drying of soybean seeds were studied and the process was modeled Results showed that values of the energy efficiency (33 70 to 66 0%) were higher than exergy efficiency (23 38 - 48 30%)

Advanced Technology in Heat and Mass Transfer Each of the types of dryer and cooler are suited to specific applications: Continuous Fluid Bed Features Extremely high heat transfer coefficient Drying residence time adjustable May be arranged to break up lumpy materials Sanitary design permits the same machine to process different materials

Rotary dryers work by tumbling material in a rotating drum in the presence of a drying air They can also be indirectly heated to avoid direct contact between the material and processing medium The drum is positioned at a slight horizontal slope to allow gravity to assist in moving material through the drum

within the dryer heat transfer by convection and mass transfer occur simultaneously especially at the early drying stages there is no significant mass transfer effect outside the dryer Within the dryer also the heat reflected to the transparent cover is unable to escape since it is within the infrared spectrum

Seeds are broadly grouped into orthodox (desiccation-tolerant) intermediate and recalcitrant (desiccation-sensitive) based on their ability to withstand drying Whilst the protocols developed to classify seeds into one of the three groups have aided ex-situ storage of germplasm the classification of many species with seeds having a hard coat
