Abstract: This paper presents studies on usability of multilayered hybrid composite as personal armor material. In the scope of study, 4 hybrid composite materials with different number of layers and thickness have been produced by using three different type of fabric. Then, ballistic tests have been performed and results have been investigated. The ballistic tests have been performed by using Beretta and 9 mm FMJ bullet to the international standards (NIJ 0101-06). In the ballistic tests, the speed of bullets and the depth of penetration (DOP) occurring on the test samples have been measured and the damages have been assessed. First 2 test samples with [Glass fiber10/Aramid fiber10/Carbon fiber10] sequence and 30 layers have been produced, the ballistic tests have been performed and investigated. After observing the success of these two test samples, other two test samples have been produced by reducing the number of layers to 21 with [Glass fiber7/Aramid fiber7/Carbon fiber7] sequence.

Abstract: The aim of this study is to investigate forced convection heat transfer and flow characteristics in a herringbone type plate heat exchanger channels using Al2O3/water nanofluids with numerical analysis method. The numerical analysis comprises the analysis of two dimensional model of the plate heat exchanger channel. Constant heat flux is applied on the walls. The heat transfer characteristics were simulated using finite volume method with the standard k–ε turbulence model and solved iteratively by using the SIMPLE algorithm. The numerical analysis was carried out in different Reynolds (600-1900) numbers and volumetric (0.25%, 0.5%, 0.75%, 1%) concentrations for single phase approach and results got from the numerical analysis were compared with the results obtained experimentally. It was concluded that there is a good consistency between the numerical analysis and results obtained experimentally. According to the experimental study and numerical analysis (this research), heat transfer
