Abstract Convection is a phenomenon that often occurs in the presence of temperature gradients. In microgravity, free convection can not occur due to lack buoyancy. However, during parabolic flights we observed convections microparticles gas discharge within cylindrical plasma chamber setup PK-4. The and were exposed thermal gradient. There, cloud dust waves observed. Analysis by tracking micro...

The aim is to support application users to inspect the results of software that simulates complex, time-variant physical phenomena in the natural and engineering sciences. The objective is to ’perceptualise’ the Gigabytes of data by means of visual and haptic 3D animations. The quality of the animations depends, among other aspects, on the reliable synchronisation of the animation frames, indep...

Linear and nonlinear stability analyses for the onset of time-dependent convection in a horizontal layer porous medium saturated by couple-stress non-Newtonian nanofluid, intercalated between two thermally insulated plates, are presented. Brinkman Maxwell–Garnett formulations adopted nanoscale effects. A modified Darcy formulation that includes time derivative term is used momentum equation. Th...

The aim of this work was to study the infrared (IR) drying of food products. In present article the effects of blanching, of air velocity and of different air temperatures on the drying time and on the rehydration ratio as a quality property are investigated. During research different food materials were used: apple, carrot and potato. In the article a simultaneous heat and mass transfer model ...

Many recent studies have reported the presence of two types of El Niño events in observation: Cold Tongue (CT) El Niño and Warm Pool (WP) El Niño. We investigate the sensitivity of a model simulating two types of El Niño by changing a convective triggering parameter (Tokioka parameter). When deep convections are highly suppressed with a large Tokioka parameter, the model is capable of simulatin...
