	Abstract:An experimental study of subcooled flow boiling in a high-aspect-ratio, one-sided heating rectangular mini-gap channel was conducted using deionized water. The local heat transfer coefficient, onset of nucleate boiling, and flow pattern of subcooled boiling were investigated. The influence of heat flux and mass flux were studied with the aid of a high-speed camera. The results show that the flow pattern was mainly isolated bubbly flow when the narrow microchannel was placed vertically. The bubbles generated at lower mass fluxes were larger and did not easily depart, forming elongated bubbly flow and flowing upstream. The thin film evaporation mechanism dominated the entire test section due to the elongated bubbles and transient local dryout as well as rewet. The local heat transfer coefficient near the exit of the test section was larger

	Abstract:The heat transfer characteristics of supercritical China RP-3 aviation kerosene flowing downward in a vertical circular tube are numerically investigated. A ten-species surrogate model is used to calculate the thermophysical properties of kerosene and the Re-Normalization Group (RNG) k-ε model with the enhanced wall treatment is adopted to simulate the turbulent flow. The effects of diameter, wall heat flux, and pressure on temperature and heat transfer coefficient are studied. The numerical results show three types of heat transfer deterioration exist along the flow direction. The first deterioration at the tube inlet region is caused by the development of the thermal boundary layer, which exist whatever the operation condition is. The second and third kind of deterioration take place when the inner wall temperature or the bulk fuel temperature approaches the pseudo-critical temperature under a pressure close to the critical value. The heat transfer coefficients increase with decreasing diameter and increasing pressure. The increase of inlet pressure can effectively eliminate the deteriorations because the thermophysical properties change less near the critical point at higher pressure. The decrease of wall heat flux will delay the onsets of the second and third kind of deterioration. The numerical heat transfer coefficient fit well with the empirical correlations

	Abstract:In this paper, molecular dynamics simulations have been performed on poly(vinyl alcohol)-cryoprotective agent solutions. Four cryoprotective agents (CPA) were selected: DMSO, ethanol, ethylene glycol and glycerol. Hydrogen bonds were analyzed based on a geometrical criterion. The results showed that the number of hydroxyl groups in CPA molecules had a great impact on hydrogen bonding structure of PVA-CPA aqueous solutions.

	Abstract:Difficulties for the conventional computational fluid dynamics and standard lattice Boltzmann method to study the gas oscillating patterns in a resonator are discussed. In light of the recent progresses in the lattice Boltzmann method world, we are now able to deal with the compressibility and non-linear shock wave effects in the resonator. The implicit-explicit finite-difference lattice Boltzmann method is used to investigate such problem. In particular, a lattice Boltzmann model for viscid compressible flows is introduced firstly. Then, the Boltzmann equation with Bhatnagar-Gross-Krook approximation is solved by a finite-difference method with the third-order implicit-explicit Runge-Kutta scheme for time discretization, and the fifth-order WENO scheme for space discretization. Numerical results obtained in this study agree quantitatively well with available experimental data and simulation results using conventional numerical methods. Moreover, with the implicit-explicit finite-difference lattice Boltzmann method, the computational convergence rate can be significantly improved compared with the previous finite-difference and standard lattice Boltzmann method. This work is carried out as the first effort to study phenomena in thermoacoustics engines with lattice Boltzmann method.
