How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more
Ali Dawood Salman currently works at the Department of Mechanical Engineering/RAC, University of Technology. Their most recent publication is 'Thermal Efficiency for Passive Solar Chimny With and Without Storage Material'.
A paraffin wax and copper foam matrix were used as a thermal energy storage material in the double passes air solar chimney (SC) collector to get ventilation effect through daytime and after sunset. Air SC collector was installed in the south wall of an insulated test room and tested with different working angles (30 o , 45 o and 60 o ). Different...
In this work, a test room was built in Baghdad city, with selective dimensions, while the solar chimneys (SC) where designed with aspect ratio (ar) bigger than 12 and setup to the oriented wall to the south. Collector of SC consist of paraffin wax as a phase change material (PCM) and supported by copper foam matrix (CFM), to enhance the combined o...
In this experimental work, semi full scale insulated test room is built with (2*1.5*1.5) m3, in Baghdad city. Test room was supplied by three types of solar collectors, where heat are stored in a thermal energy storage box (TESB). The TESB was made from phase change material (PCM) that supported by metal foam, to enhance the thermal conductivity, b...
In this present work computational models are fabricated , these model depended on the elements of longitudinal finned tube to design the roll bound evaporator. The computational models consist of empirical and mathematical correlation beside values of each design variables and variable boundaries that is obtained from experimental tests. The desig...
In this study, a different design of passive air Solar Chimney(SC)was tested by installing it in the south wall of insulated test room in Baghdad city. The SC was designed from vertical and inclined parts connected serially together, the vertical SC (first part) has a single pass and Thermal Energy Storage Box Collector (TESB (refined paraffin wax...
In this study, a practical study was conducted to compare the efficient behavior of close loop solar water heater with thermosiphon- riser tubes with dimensions (80 cm width, 120 cm height) with two acrylic covering. both with and without thermal performance enhancer, and to find the optimum mode of convection in the collector. the thermal performa...
In this study, a hybrid system is developed with combined of vapour compression refrigeration (VCR) and thermoelectric cooling (TEC) systems. VCRs operate as a secondary system to absorb the heat released by the primary system, TEC. The hybrid system comprises two compartments: a freezer for storing vaccines at low temperatures with TEC modules and...
Thermoelectric coolers (TEC) are devices that conversion of electrical power into a temperature gradient. TEC modules have the benefits of high dependability, small dimensions, lightweight, absence of mechanical moving parts and working fluid. Thermoelectric cooling systems have experienced significant utilisation in recent years. These technologie...
Simulation to determine the adiabatic capillary tube critical length for HFC, HCFC and hydrocarbon refrigerants
A paraffin wax and copper foam matrix were used as a thermal energy storage material in the double passes air solar chimney (SC) collector to get ventilation effect through daytime and after sunset. Air SC collector was installed in the south wall of an insulated test room and tested with different working angles (30 o , 45 o and 60 o). Different S...
This study presents experimental work to construct a non- conventional thermosyphon where it is consists of three parts, which include the evaporator, adiabatic and condenser sections all of these parts are arranged radially in parallel to construct the heat valve (HV). Heat valve used to evacuate heat from horizontal copper electrical heater tube...
This experimental study investigated the change in cross-sectional area (csa) of thermosyphon's condenser to it's a constant perimeter (RAP) and effect of that at the thermal performance. Geometries shapes deform from circular to elliptical and flat to make a change in csa at a same perimeter of all geometries shapes where a different value of RAP...
Greeting for everybody
My question for estimating cooling load for any building consist of lighting
so how can calculate the cooling load for lighting ( LED lighting)
with my respect
I am planning to build a heat pipe with composite material wick ( from copper and aluminum powder in different percentage of component), if anyone have a practical idea to adhesive the different particles of the material powder together.
Greeting for every one
My question is; how to simulate the thermoelectric cooling chipset ( Peltier) in simple method by employing Fluent
where my new project to enhancement the CPU and GPU cooling by employing Peltier.
