Abstract

Vapor pressures and saturated liquid molar volumes of hydrocarbons up to n-C16 were predicted using equations of states. The equations of states used were Redlich-Kwong (RK), Mohsen Nia et al.-Redlich-Kwong (MRK), Saave-Redlich-Kwong (SRK), and Peng-Robinson (PR). The calculated values were compared to the experimental data extracted from various sources. The results indicated that PR eos was superior among the others.

Abstract

The FLUENT V4.25 program is the CFD (Computational Fluid Dynamics) simulation. It can be used for fluid flow and heat transfer analyses and others. Regarding the program, the test is needed to know the validity, to verify that the program will give good output. Based on the test using experimental data on four heated parallel rod bundles, the output FL UENT V4.25, it gave a good result, where the differences between calculation and experimental data are not significant. It is expected that the FLUENT V4. 25 program may achieve success in thermo-hydraulic analysis on other similar systems.

Abstract

Non-conventional cutting is required for quality production which is usually difficult to be achieved by conventional cutting. Besides non-conventional cutting provides advantages in simplified cutting process and its flexibility. This paper describes the theory of non-conventional cutting process using abrasive water-jet, the design and manufacturing of the cutter and also the performance testing.

Abstract

This paper describes the motivation and design criteria for the development of a couple-tank control system which is intended to be used as a demonstration apparatus for a lecture course on Introduction to Control Systems. The work also demonstrates the performances of the controlled system in tracking various types of command inputs, Control strategies implemented to the system are On-Off control, Proportional control and Proportional-Integral control. Influences of dynamic interaction between channels on the performance degradation are also shown in this work. Except as a control system design example, this work is expected to be useful to mechanical engineering lecturers giving courses on Introduction to Control Systems, particularly to those in private universities.

Abstract

Pencocokan setiap komponen PLTGU bisa dilakukan dengan sualu program simulasi. Pada penelitian ini, simulasi keadaan tunak dibuat untuk PLTGU Tanjung Priuk dengan beberapa penyederhanaan. Tiap blok PLTGU tersebut terdiri dari 3 buah siklus gas dan 1 buah siklus uap dengan 3 buah HRSG. Data yang diambil dari ruang kontrol diolah untuk mendapatkan persamaan karakteristik garis operasi dari setiap komponen. Selanjutnya program simulasi dibuat berdasarkan persamaan-persamaan tersebut bersama-sama dengan persamaan persamaan fisik lainnya sehingga terbentuk sistem persamaan simultan 47 persamaan dengan 47 variabel. Program simulasi ternyata bisa mencapai nilai konvergen untuk berbagai input beban (daya total) serta menunjukkan kecenderungan yang sama dengan data ruang kontrol, khususnya dalam hal efisiensi siklus kotor (bruto).

Abstract

This paper describes dynamic modeling and model validation of a couple-tank control system which consist of a couple-tank, two motor-and-pumps, two electric-motor drivers, and two water-level sensors. Initially, dynamic modeling of the couple-tank was derived analytically. This derivation produced several parameters whose values were unknown. Experiments were then performed in order to obtain the values of those parameters. In addition to the couple-tank, other components were also modeled statically. Once all components of the couple-tank controlled system have been modeled, model validation of the whole system can then be performed.

Abstract

To simulate the thermohydraulic characteristics of reflooding process of a nuclear core reactor during lost of cooling accident, an experimental study using a reduced model was carried-out. The core reactor model consists of a 50 mm tubular transparent shell made of quartz and a bundle of 4 zircaloy-4 pipes of equal diameter 10.7 mm which are equipped with electrical heaters in the inside. The configuration of pipe bundle is in-line with the distance between pipe axis is 14.2 mm. The pipes are identic to those usually used as nuclear reactor fuel claddings. The quenching process was done by flooding the pipe bundle from the bottom. The observation temperature drop of the pipes surface and temperature rise of cooling water for various wetting velocity, initial pipe temperature and cooling water were recorded and analyzed. The quenching phenomenon was also observed visually. The initial pipe temperature and wetting velocity range are 100 - 500 "C and 4 - 20 cm/s, respectively.

Abstract

In this paper, moisture absorption process in composite material was analytically and experimentally studied. The environmental condition was 72o C and 85 % RH. During a fixed interval time, the composite specimens were taken out from the experimental chamber and weighted. The weight gain showed that the absorption isoterm profile followed Fick Law andthere was a good agreement between the analytical and experimental results. The average maximum moisture absorption was 0.84 %.

Abstract

This paper presents an optimization technique applying the design of the cyclone separators. The results of this optimization technique were the main geometric ratio of the modified cyclone (DOPOL), which presented in non-dimensional form, that satisfied the following criteria: minimum pressure drop or maximum separation efficiency. The design procedure of the cyclone was written as the computer software, where the iterative computation design can be proceed faster. This software used the correlations of the cyclone performance obtained by the previous experimental on a modified cyclone. The software not only could be applied for modified cyclone design, but it also could be used for the design of the classical cyclone base on the well-known algorithm.
