Abstract: This paper presents experimental investigations on the effects of liquid properties on pressure drop for both single-phase and two-phase flows through sudden contraction in horizontal rectangular minichannel. In order to know the effects, water and viscoelastic liquid, namely 0.1 wt% polyacrylamide (PAM) aqueous solution are selected as the working liquid, while air as the working gas. Liquid single-phase and air-liquid twophase flow experiments were conducted at room temperature using a horizontal rectangular mini-channel with a sudden contraction. The cross-sectional dimensions of the channel with the height (H), the width (W) and the hydraulic diameter (DH) for the narrow channel are 2.79 mm, 3.09 mm and 2.94 mm, while those for the wide channel are 2.95 mm, 5.98 mm and 3.95 mm. The local pressure upstream and downstream from the contraction were measured with calibrated pressure transducer to determine the pressure drop due to the contraction. As an analysis, the resulting data on

Abstract: Problem solving is a fundamental element in retaining and achieving operational excellence of a manufacturing industry. There are numerous problem solving models are being used widely but the problem is to determine an optimal or a poka-yoke solution according to the constraints of respective manufacturing industry. Nevertheless, optimal solution for problems has become a great challenge in view of the fact that existing problem solving model is highly vague where at times it is being neglected either due to ineffective or too complex. This leads to individual getting confused and not able to devote their time successfully on any of the problem solving models. The most common approach of problem solving model is via trial-error or insight pattern where problems are being tackled and resolved in a quick manner, which it eventually contains the problem, instead of identifying the actual root cause and resolve the problem for good. The paper will discuss on a newly developed model based s
