[ 1 ] - طراحی الگوریتم دستورالعمل نرم افزاری ممیزی انرژی در مجتمع های مسکونی
زمینه و هدف انجام ممیزی انرژی در ساختمان ها با کاربری های مختلف از جمله مواردی است که در جهت صرفه جویی و کاهش مصرف انرژی هر چه بیش تر مورد توجه قرار گرفته است. انجام ممیزی در هر کاربری روش خاص خود را می طلبد، از جمله در بخش ساختمان های مسکونی.از آن جای که فن اوری به کار گرفته شده در مصارف انرژی در ساختمان ها درکشورهای مختلف متفاوت است و به منظور عرضه یک روش ملی در انجام این امر، ضروری است که ...
[ 2 ] - Optimization of Heat Transfer Enhancement of a Domestic Gas Burner Based on Pareto Genetic Algorithm: Experimental and Numerical Approach
The present study attempts to improve heat transfer efficiency of a domestic gas burner by enhancing heat transfer from flue gases. Heat transfer can be augmented using the obstacles that are inserted into the flow field near the heated wall of the domestic gas burner. First, to achive the maximum efficiency, the insert geometry is optimized by the multi-objective genetic algorithm so that heat...
[ 3 ] - Application of Single Objective Genetic Algorithm to Optimize Heat Transfer Enhancement from a Flat Plate
The optimal shape of a two dimensional turbulator above an isothermal flat plate is found by using numerical simulation. The turbulent boundary layer over the flat plate was disrupted at various situations by inserting a quadrilateral bar where the boundary layer thickness kept more than three times greater than the insert\'s height. As a result, the overall heat transfer coefficient of the wal...
[ 4 ] - Optimization of Heat Transfer Enhancement of a Flat Plate Based on Pareto Genetic Algorithm
A quad inserted into a turbulent boundary layer of a flat plate and its effect on average heat transfer and the friction coefficient is studied. To optimize this effect, the edge sizes and distance of the quad from the flat plate are continually modified. In each case, simultaneously the heat transfer enhancement and reduction in skin friction are analyzed. For optimization, the genetic algorit...
[ 5 ] - The Effect of Square Splittered and Unsplittered Rods in Flat Plate Heat Transfer Enhancement
A square splittered and unsplittered rod is placed in a turbulent boundary layer developed over a flat plate. The effect of the resulting disturbances on the local heat transfer coefficient is then studied. In both cases the square rod modifies the flow structure inside the boundary layer. As a result, a stagnation point, a jet and wake area are generated around the square rod, each making a co...
