A two-dimensional (2D) lattice Boltzmann method (LBM)-cellular automaton model is presented to investigate the dendritic growth of binary alloys in the presence of natural convection. The kinetic-based LBM is adopted to calculate the transport phenomena by the evolution of distribution functions of moving pseudo-particles. To numerically solve natural convection thermal and solute transport sim...

We describe a simple method of determining weight loss and hence water loss of infants in incubators. Unlike previously reported methods, it does not interfere with the microenvironment surrounding the infant. Weight loss of 16 term and 32 preterm infants was measured in both forced and natural convection. No significant increase in water loss was observed in the term infants but in the preterm...

Results are presented from a series of analytical and numerical studies of buoyantly driven flows along heated vertical surfaces immersed in stably stratified fluids. Flows of the studied type are broadly represented in engineering and geophysical applications. First, the classical problem of one-dimensional natural convection flow along a heated wall is revisited for the case of a stably strat...

The present experimental study reports the thermal performance analysis of a phase change material (PCM)-basedfinned heat sink placed on silicone rubber heater which mimics CPU chip and is cooled by natural forced convection. subjected to constant cyclic loading for five input power values (4, 6, 8, 10, 12 W). Paraffin wax 1-hexadecanol are selected as PCM this study, have melting points in ran...

in this study, the effect of wall orientation on the optimum insulation position in the wall from different perspectives is studied numerically. using crank- nicolson one dimensional transient heat conduction equation is solved for the wall with convection boundary conditions. outdoor temperature is considered as a periodic function of time. since natural night ventilation is used in the buildi...

An overview of experimental transport studies performed on the Rijnhuizen Tokamak Project (RTP) using transient transport techniques in both Ohmic and ECH dominated plasmas is presented. Modulated Electron Cyclotron Heating (ECH) and oblique pellet injection (OPI) have been used to induce electron temperature (Te) perturbations at different radial locations. These were used to probe the electro...
