There are some problems with estimating time of manufacturing process of products, especially when there is variable serving time, like control stage. These problems will cause overestimation of process time. Layout constraints, reworking constraints and inflexible product schedule in multi product lines, needs a precise planning to reduce volume of line stock. In this article, by analyzing real queue...
In this paper, based on the mechanism of artificial roughness on thermal transfer enhancement and the characteristic of TV panel mould, two improved solutions for cooling structure of the mould are given and simulated. The calculation results show that the artificial roughness interposed on the outer surface of the caviry plate can enhance greatly the thermal transfer efficiency, and the heigh and...
This paper presents a formula based on simulation results using Fluent software to determine the size and position of a spiral cooling channel in a plastic injection mold that yields the maximum effect on the ratio of product cooling rates and coolant pumping energy (CR/PE). In this formulation, there are 5 simulation steps performed: Re, Ac/Ap, Lc/Lp, rca/rp and kmold. The formulat was developed...
The most promising applications for standing-wave thermoacoustic cooling were investigated from the perspective of the ratio of coefficient of performance (COP) to the reversible COP or COPR. A design optimization program based on the thermoacoustic simulation program known as DELTAE was developed. The program was applied to two standing-wave thermoacoustic cooler configurations in order to determine...
