From theCambridge English Corpus The definition ofconvectionvelocity used for the present work is precisely the same as that used in the previous plane boundary-layer experiments. From theCambridge English Corpus The system reaches a near steady-stateconvectionpattern. From theCambridge English Corpus In that case the basic patterns are traveling pulses which arise in theconvectionof binary fluids. From theCambridge English Corpus A phase-locked flow-visualization technique was adopted for determining theconvectionvelocities of the two types of vortices during the pairing event. From theCambridge English Corpus One obvious method to suppress higher-dimensional behaviour inconvectionin rectangular containers is t o use narrowconvectioncells. From theCambridge English Corpus Vigorous compositionalconvectionfrom the growth of the basal crystals can also be seen. From theCambridge English Corpus This article describes experimental work on the mixedconvectionregime with flow normal to electrically heated cylinders. From theCambridge English Corpus We describe experiments onconvectionin binary fluid mixtures in a large-aspectratio annular container. From theCambridge English Corpus The large-scale motions transport by simpleconvectionof fluid packets while there is smaller scale transport by gradient diffusion. From theCambridge English Corpus For example, the observed trends for energy transport in a round free jet flow is by the large-scaleconvectionmotions. From theCambridge English Corpus This minimizesconvectionof points that leads to uneven node point distributions and is a principal cause of numerical difficulties. From theCambridge English Corpus Transient uplift is probably generated by temporal and spatial variations in mantleconvection. From theCambridge English Corpus The book is broad in scope, bringing in such aspects as the constraints of seismic topography, and mantleconvectionin other planetary bodies. From theCambridge English Corpus The thicknesses of these boundary layers are of the same order because the relevant speeds ofconvectionare the same for both.
