ABSFDMThis paper presents a numerical study of melt flow behaviour of ABS plastic through the melt flow tube of the liquefier head of the Fused Deposition Modelling (FDM) rapid prototyping process using the finite element analysis. Main flow parameters including temperature, velocity and pressure ...
The approach is generally assumed to be reliable at lower elevations (below 3500 m above sea level, a.s.l) where air temperature (Ta) relates well to the energy inputs driving melt. We question this approach in High Mountain Asia (HMA). We study in-situ meteorological drivers of ...
For FD to be feasible, themelt viscosityin the liquifier should be low enough so that the cold filament can force the molten material out of the nozzle. Filaments with highmelt viscosityrequire either a high strength or ahigher operating temperatureto lower the melt viscosity to make FD feasib...
The effect of sinusoidal temperature fluctuations in the melt on the growth of a crystal is investigated by solving the concentration-diffusion and heat-conduction equations for both solid and liquid phases in a linear approximation. The response of the temperature and concentration at the interface ...

This simulation was achieved using temperature lapse rates of -0.4 to -0.45 °C/100 m during the summer monsoon period, a degree/day factor of 6 to 8 l/(m2*day*°C), and the decrease of precipitation with approximately 7% per 100-meter altitude. Although many assumptions have to be ...
Based on the conservation of energy, the distribution density of induction current was ascertained. With the program, the relationship between melting power, charge weight, and melt temperature was established. During induction skull melting of gamma-TiAl based alloys, the melt temperature was measured...

Recent warming and freshening of the Canada Basin has led to the year-round storage of solar radiation as the near-surface temperature maximum (NSTM). Using year-round ocean (from ice tethered profilers and autonomous ocean flux buoys), sea-ice (from ice mass balance buoys), and atmosphere ...
