Technology Reports of Kansai University (ISSN: 04532198) is a monthly peer-reviewed and open-access international Journal. It was first built in 1959 and officially in 1975 till now by kansai university, japan. The journal covers all sort of engineering topic, mathematics and physics. Technology Reports of Kansai University (TRKU) was closed access journal until 2017. After that TRKU became open access journal. TRKU is a scopus indexed journal and directly run by faculty of engineering, kansai university.

Response surface methodology was used to determine for optimum processing condition that yield maximum water loss and weight reduction and minimum solid gain during osmotic dehydration of radish in salt solution. The experiments were conducted according to Box-Behnken Design. The independent process variables for osmotic dehydration were processing time (30-120min), temperature (40-60°C) and salt concentration (6-10%w/w). The osmotic dehydration process was optimized for water loss, solid gain, and weight reduction. The optimum conditions were found to be; temperature = 44.575°C, immersion time =30min, salt concentration =6%. At this optimum point, water loss, solid gain and weight reduction were found to be (27.87g/100g initial sample), (1.05g/100g initial sample) and (26.83 g/100g initial sample), respectively
Nowadays, the study on fluid flow over bluff bodies is utmost important and as a fundamental topic in fluid mechanics. Generally, when a bluff body is immersed in a fluid flow, a strong tonal noise or whistle-liked noise will produce. This sound is known as Aeolian tones. This study will investigate the Aeolian tones radiated by flow past two square cylinders in a tandem arrangement. Two rigid flat plates placed in the wake of two square cylinders are investigated numerically at Reynolds number of 150, 500, 1000, 2500 and 5000. Computational Fluid Dynamic (CFD) with ANSYS Software is used to do the simulation. Two types of flow are observed at different Reynolds numbers. At low Reynolds number, the vortex formation easily occurs. Typically, the Von Karman Street Vortex is more clearly observed in low Reynolds number. At high Reynolds number, the characteristic of the flow propagation shows similar patterns. Less entrainment of the flow occurred and the vortex is reattached together formed a streamline at high Reynolds number. The sound produced is measured by using the acoustic power level. The higher the Reynolds number, the higher the sound occupied at the vicinity of the cylinders. The maximum acoustic power level is 42.7 dB which occurred at gap length G=3.0 D
