The nucleate boiling process is known to be a very efficient mode of heat transfer. It is desirable to operate many engineering applications in this mode since high heat transfer rates and convection coefficients are associated with small values of the excess temperature. Despite its importance, nucleate boiling has not been fully numerically simulated until very recently because of the complex...

The cooling of the steel strip in ROT (run out table) of the hot rolling process is very important in that the ROT is the final process to control the mechanical properties of the final products. In general the products are cooled by the circular water jets which makes the comparatively thick residual water layer about 100–200 mm with the supplied flow rate on the plate. The basic phenomenon go...

The effects of high-temperature sterilization methods (boiling, dry-heating, autoclaving and chemiclaving) on the properties of four types of stone cast were determined. SEM observations were made of the cast surface before and after sterilization. High-temperature sterilization affected the properties of the stone casts. Boiling, dry-heating and autoclaving were considered to be unacceptable m...

the subjects of heat transfer and cooling system are very important topics in the internal combustion engines (ice). in modern cooling systems, low weight, small size and high compactness are the critical designing criteria that requires heat transfer enhancement. boiling phenomenon which is occurred in the water jacket of the ice is one of the methods to increase heat transfer in the coolant s...

A compact packaging module for direct liquid cooling of roomtemperature quantum cascade lasers is implemented. The light was coupled out of the hermetically sealed package through a mid-infrared fibre epoxy-bonded to the laser. The threshold current reduces by 10%, compared to convectional substrate-side cooled lasers when using low boiling temperature (boiling point (b.p.)1⁄4 34 C) 3M HFE7000 ...
