The liquid droplet cooling technique for fast scanning chip calorimetry (FSC) is introduced, increasing the rate large samples on a given sensor. Reaching higher rates and using gas as medium, common standard ultra-fast temperature control in requires reducing lateral dimensions of sample maximum limited by heat capacity exchange between sample. enhanced performance new demonstrated both metals...

complex heat transfer phenomena (including unsteady state conduction, convection and solidification processes) occur in steel belt conveyer sulfur granulating method. numerical simulation of this technique is performed via a comprehensive and multifaceted one dimensional model. since the air situated between the adjacent sulfur pastilles is essentially stagnant, therefore, the surface temperatu...

This work aims to achieve deep insight into the phenomenon of phase transformation upon rapid cooling in metal systems and reveal the physical meaning of scatter in the time taken to reach crystallization. The total number of pure metals considered in this work accounts for 14. Taking pure copper as an example, the correlation between phase selection of crystal or glass and cooling rate was inv...

Quenching cooling rate of rotary hollow cylinder by one row of water impinging jets has been experimentally studied. Water jets (d = 8 mm) with sub-cooling 55 to 85 ◦C and Reynolds number 8,006 to 36,738 impinged over rotary hot hollow cylinder (rotation speed 10 to 70 rpm) with initial temperature 250 to 600 ◦C. Impingement impact angle of row of jets varied between 0 to 135 ◦ and jet-to-jet s...

We tested the efficacy of pethidine and cutaneous warming to prevent shivering during percutaneous cooling in unanaesthetized patients. Ten patients scheduled for cranial neurosurgery received pethidine infusion and skin warming. The Setpoint internal heat-exchanging catheter was inserted and cooling to 33.5 degrees C was started. Clonidine and chlorpromazine were given as "rescue medication" t...

Using density-functional molecular dynamics simulations we analyzed the cooling-rate effects on the physical properties of GeS2 chalcogenide glasses. Liquid samples were cooled linearly in time according to T (t) = T0 − γt where γ is the cooling rate. We found that our model leads to a promising description of the glass transition temperature Tg as a function of γ and gives a correct Tg for exp...

The rheology and microstructure of a rennet casein system were studied in the pH range from 5.8 to 12.0 during cooling from 80 to 5 degrees C at four cooling rates: 0.5, 0.1, 0.05, and 0.025 degrees C/min. A dramatic increase in storage modulus with pH was observed during cooling at a fixed cooling rate. Continuous networks were formed for gels at pH 7.2 and above, while a discontinuous network...

Quantum theory of optical stochastic cooling is presented. Results include a full quantum analysis of the interaction of the beam with radiation in the undulators and in the quantum amplifier. A density matrix of the whole system is constructed and the cooling rate is evaluated. It is shown that quantum fluctuations change classical results of stochastic cooling at low bunch population and set ...

It has been shown experimentally by many researchers that cooling rate and crystallization temperature affect the rate of crystal formation. In this study, crystallization kinetics of coconut oil was measured by monitoring the solid fraction of the oil using pulsed Nuclear Magnetic Resonance (pNMR). Four levels of cooling rate and crytallization temperature were studied. Parameters of crystalli...
