Deep understanding the nucleate flow boiling heat transfer mechanism of salt solutions is of great importance for the design and safe operation of modern steam power equipment. In this work, the nucleate flow boiling for NaCl solution and pure water was experimentally studied within the concentration...

Calibration corrections for the calorimeter were found to depend strongly on the heat capacity of the solution being measured. Measurements of the heat capacity of NaCl(aq), from 1 to 6 mol · kg 1, are reported to 598 K at 20 MPa and at 523 K to 36 MPa. Comparison with literature ...
Heat treatment can modify the corrosion resistance of stainless steels. Thus, the corrosion behavior of ASTM A890/A 890M GR 5A super duplex stainless steels (SDSS) has been investigated in aqueous 60,000 ppm NaCl solution by several electrochemical tests. The specimens were aged for 2, 10, ...
The charge on the surface of protein could be neutralized by NaCl, while the H+ in the charged amino groups on the surface of protein could be released into solution by NaCl, thus reducing the thickness of protein electric double layer (Cheung, Wanasundara, & Nickerson, 2014) and decreasing...
The equipment opens up high-temperature aqueous-solution chemistry for rapid and accurate investigation. The heat capacity of aqueous NaCl from 0.1 to 3.0 mol kg 1 has been measured from 325 to 600 K and 17.7 MPa. Additional measurements have been made at 320.55 K and 1.0 MPa as well as ...
Under the conditions of a water solution with a quartz sand slurry containing H 2 SO 4 and NaCl, 7ms 1 nominal test speed, and 45° test angle, the erosion properties of the stainless steel were improved by the laser-clad Ni-base alloy. After applying heat treatment to the clad layer,...
Solution treatment at a relatively high temperature to dissolve Cu- and Mg-rich particles formed during solidification to achieve a high and homogeneous concentration of the alloying elements in solid solution. 2. Quenching, usually to room temperature, to obtain a supersaturated solid solution of sol...
The field (geometrical) theory of specific heat is based on the universal thermal sum, a new mathematical tool derived from the evolution equation in the Euclidean four-dimensional spacetime, with the closed time coordinate. This theory made it possible
