Fluent is one of the commercial software of computational fluid dynamics using a finite volume of discritization method.This method devides a domain of model becoming several small finite volumes. This software may be used to predict the fluid flow, heat transfer, chemical reaction and other fluids phenomena. In the recent study, the Fluent is used as a tool to predict the characteristics of air and partial exhaust gas mixtures in an intake manifold of diesel engine.In this modeling, the observed mixtures characteristics are the fluid flow and temperature distributions. The type of fluid flowing in the intake manifold of EGR is a turbulent flow. Fluent serves some turbulence models which are k-Îµ, k-Ï‰ and Reynolds Stress Model (RSM) models. Each turbulence model has a different characteristics. It is important, therefore, to know the appropriate turbulence model type for investigating the fluid flow mixtures phenomena in the intake manifold. The fluids flowing into this intake manifold are varied based on the percentage of opening valve EGR, opening load valve and diesel engine speeds. The study shows that the k-Îµ turbulence model is the best model than the other models. This turbulence model has small error with the experimental results for several the opening load valves in which for opening load valve of 0% (0.374% error), 50% (0,495% error), 75% (0,444% error) dan 100% (0,505% error). However, the k-ï· turbulence model has the smallest error (0.381%) at the opening load valve of 25%.

Fin and tube heat exchangers use gas as a cooling/heating medium on the fin side. The low thermal conductivity of gases results in high thermal resistance, which results in a low rate of heat transfer. Therefore, the researchers sought to reduce thermal resistance on the fin side. This study aims to increase heat transfer by reducing thermal resistance using a longitudinal vortex generator. However, the use of vortex generators will increase the pressure drop. Perforated vortex generators were investigated in this study to overcome this problem. Concave rectangular winglet vortex generator at an angle of attack of 30Â° with variations of without hole, one, two, and three holes were studied. In this experiment, the number of pairs of vortex generators was varied from one to three pairs. A plate on which the vortex generator is mounted is heated at a heat rate of 35 W. Air enters the channel through the straightener at variations in the velocity of 0.4 m/s to 2 m/s at intervals of 0.2 m/s. The results showed that the value of the convection heat transfer coefficient for the use of perforated concave rectangular winglet vortex generators was 85.4% higher than the baseline. This value is 13.7% higher than the use of perforated rectangular winglet vortex generators. Whereas the value of pressure drop for the use of perforated concave rectangular winglet vortex generators is five times higher than that of the baseline. This value is 104.9% higher than the use of perforated rectangular winglet vortex generators.

Curling phenomenon on rapid prototyping (RP) product is an actual problem which has not been solved clearly, also on MMD-Is product. Previous experiment showed, it was caused dominantly by un-uniformity of temperature distribution in build part system when sintering was executed. Differ to the sintering process in the common commercial RP process, sintering process in MMD-Is is conducted in supporting powder media. The research is aimed to observe the effect of supporting powder materials, particle size and configuration of heater system on temperature distribution of the build part. Temperature distribution was measured by immersing thermocouples into supporting powder in vertical and horizontal formation. The experimental results show that the un-uniformity of the build part temperature is caused by secondary heating phenomenon by piston material at base position.
