Fully developed incompressible turbulent Flow in two-dimensional channel with turbulence promoters has been predicted numerically by large eddy simulation, Parameter C in Smagorinsky model can be assumed constant generally in the range of high Reynolds. In this paper, C is varied with SGS Reynolds number in low Reynolds number region and SGS eddy diffusivity near the solid boundary is considered as a function of the distance from the boundary, the velocity gradient and the molecular viscosity, There improvements of SGS eddy viscosity model and the boundary condition of SGS eddy diffusivity have little effects on the mean velocity distribution, but have a significant effect on distributions of turbulence and turbulent shear stress. Computed streaklines and Strouhal number of vortex shedding behind the turbulence promoter are compared with visual experiments. The Reynolds number in computation is set at 1.1 × 10
4 and 9000 grid are distributed.

the measurements of the vapor-liquid coexistence curve in the critical region for R 114 (C
2CL
2F
4) were made by visual observation of the disappearance of the meniscus at the vapor-liquid interface within an optical cell. Twenty-three saturated densities between 410 K and critical temperature were obtained in the range of densities 290 to 894 kg/m
3. The experimental errors of temperature and density were estimated within ±0.5%, respectively. On the basis of there results, the critical temperature T
c and the critical density ρ
c for R114 were determined to be 418.78 K and 576 kg/m
3, respectively, in consideration of the disappearing meniscus level as well as the intensity of the critical opalescence. The critical pressure p
c for R114 was calculated to be 3.252 Mpa by the available vapor-pressure correlation with the present value of T
c. In addition, the critical exponent β and the low of rectilinear diameter near the critical point were also discussed.

The heat transfer coefficient distributions around a cylinder attached tripping wires in cross Flow were measured at a Reynold number of R
e=5×10
4 for various diameters and positions of the wires. The heat transfer coefficient distributions measured could be classified into three patterns, corresponding well to that of the pressure distribution around the cylinder. The mean heat transfer coefficient and drag coefficient of the second pattern showed 20% increase and 50% decrease, respectively, compared with those of the bare cylinder.

The coolant channels formed by joining together two metal sheets, one or both of which are embossed or corrugated to form a channel shape, have been proposed so far for one of the first walls of a nuclear fusion reactor. This paper deals with the heat transfer of a Flow in triangular ducts or ducts consisting of a flat plate and a sine curve embossed half channel; the walls are partly heated with high fluxes. The effects of secondary Flow, heat conduction within materials and radiation heat exchange among walls each other to laminar convective heat transfer of an asymmetrically heated ducts are theoretically examined. Numerical results show that heat conduction within wall contributes to the increase of heat transfer rate. The factor j/f in the developing region of velocity and temperature fields in obtained to estimate the heat transfer performance.

This paper describes an experimental study on impinging jet heat transfer of gaseous solid suspension Flow. Impinging jet is a typical examine of nonstraight Flow wherein heat transfer performance can be improved to a great extant due to the inertia difference between both phases. In the present study, the surface upon which the jet impinges is concaved so that the heat transfer enhancement due to the presence of the suspended solid particles in not confined within somewhat narrower impinging region but in extended to the wall jet region. Experimental results reveal that the observed increase in the convective heat transfer coefficient due to the presence of the solid phase exceeds the usual contribution of the increased heat capacity of the Flowing media and the merit of using the concaved for the heat transfer enhancement is apparent.

Reduction of Particulate emissions from diesel in an important theme from the view point of air pollution. Experiments were carried out using a four-stroke single cylinder direct-injection diesel engine. A new method to measure diesel particulates has been developed. Particulates were sampled with a freezing method just behind an exhaust valve and examined through a scanning electron microscope. Shape, structure and the size distribution of particulates obtained with the above method were measured under wide operating conditions. The total mass of particulate emissions was measured using a dilution tunnel sampling system. The heat release processes were analyzed using indicator diagrams ant the relation between burning conditions and particulate emissions was discussed, after systematic experiments under constant revolution speed of 2000rpm for several load and injection timing condition.

A simulation model predicting the heat release rate of a transient free spray flame which was proposed in the previous paper was improved : (1) the break up and evaporation delay was introduced ; (2) the definition of flame region was changed; and (3) the turbulent energy dissipation model was assumed for the combustion after the end of fuel injection. And it was confirmed that the improved model could successfully simulate the rate of heat release of a diesel flame in the quiescent chamber of a rapid compression machine.
