Analysis of Flux-Base Fins for Estimation of Heat Transfer Coefficient
Exact solutions are given for the transient temperature in flux-base fins with the method of Green’s functions (GF) in the form of infinite series for three different tip conditions. The speed of convergence is improved by replacing the steady part by a closed-form steady solution. For the insulated-tip case, a quasi-steady solution is presented. Numerical values are presented and the condition...
متن کاملPrediction of Heat Transfer Coefficient for Thermal Regenerators
Correlation of heat transfer coefficients for air flow through the regenerator constructed from randomly paked spheres is reported for the symmetric-balanced mode of operation. The experimental results have been correlated by the least square regression has been obtained.The present correlation has been compared with the heat transfer coefficient correlations in the literature.

در این پایان نامه نشان داده ایم که چگونه می توان مدل ریسک بیمه ای اسپیرر اندرسون را به کمک زنجیره های مارکوف تعریف کرد. سپس به کمک روش های آنالیز ماتریسی احتمال برشکستگی ، میزان مازاد در هنگام برشکستگی و میزان کسری بودجه در زمان وقوع برشکستگی را محاسبه کرده ایم. هدف ما در این پایان نامه بسیار محاسباتی و کاربردی تر از روش های است که در گذشته برای محاسبه این احتمال ارائه شده است. در ابتدا ما نشا...
15 صفحه اولInvestigation of Heat Transfer Coefficient Enhancement for CuO/TiO2 Nanocomposite in a Tube Heat Exchanger
In order to improve the efficiency and rate of heat transfer in heat exchangers, various techniques such as increasing the heat transfer coefficient are proposed. This study is devoted to the investigation of heat transfer coefficient variations due to the addition of CuO, TiO2 and CuO/TiO2 nanoparticles into a shell and tube heat exchanger. CuO/TiO2 nanocomposite was synthesized using mechanic...
