3D printers are the most common and popular method of additive manufacturing technology and provide fusion of materials using thermal effects. This phenomenon makes that temperature the most important factor affecting printing quality. The temperature is provided by the Aluminium Extruder Heat Block in the extruder and the temperature regime must be constant according to the type of printing material. The objective of this study is to make aluminium Extruder Heat Block designs with high thermal efficiency to keep the temperature regime constant and to analyse the thermal behaviour of new designs with a commercial product block design using ANSYS simulation. The materials of the blocks were chosen the same and the temperature distribution of the blocks and the average heat flux were calculated by determining the boundary conditions. The results obtained from the simulation are satisfactory when compared with the thermal behaviour of a commercial product block.

“…ANSYS Fluent software MHD module was used in the calculations. As a result, it has been observed that depending on the direction of the magnetic or electric field applied on a liquid fluid, heat transfer can be increased or weakened [12]. In order to increase the amount of heat transfer, there are options to increase the heat transfer coefficient, increase the temperature difference and increase the area based on the Fouirer equation.…”

The importance of using solar energy, one of the renewable energy sources, has started to be understood more recently. The negative environmental effects and limited amounts of fossil fuels have led to increased demand for renewable energy sources worldwide and the production of various models and devices has accelerated to take advantage of solar energy, which is the basis of all energy sources. Using solar collectors as a way to benefit from solar energy has been used for many years. Although solar collectors are generally divided into 4 types as flat plate (FPSC), evacuated tube (ETSC), parabolic (PSC) and heat pipe (HPSC), these types can also be divided into separate types with many different features. The most commonly used solar collector type in the world is Flat Plate Solar Collector. The most important reasons for this are being cheap, easily produced and applied in various ways. Yet, the thermal productivity of FPSCs decreases below 40% in non-ideal climate conditions with low surrounding temperature. The existence of such disadvantages of FPSCs led to the production of Evacuated Tube Solar Collectors. With the advancing technology, the utilization of heat pipes in collectors has come to the agenda and as a result of the studies conducted, it has been determined that the use of heat pipe improves efficiency. In addition, the use of nanofluids in solar collectors and heat pipes has become quite common, and many studies have been carried out especially on this subject recently. The primary objective is always to improve the performance of the system and achieve efficiency. In this way, solar energy will be used in the most effective way and world energy supply demand will be met by using renewable resources.

“…The minimum relative difference of the average temperature and heat flux value are 0.037% and 0.515% between the set of grids with 1,20,258 and 1,38,702 nodes. So, the set of grids with 1,38,702 nodes to 1,20,258 nodes are selected with the objective to minimize the computational time (Kelly et al, 2015; Selimli and Recebli, 2018). The adiabatic condition to the side walls of the substrate is applied by assuming zero heat flux values to the wall.…”

Heat transfer analysis is the one of the most important designing aspects for many engineering systems. The design prospect in the preview of heat transfer focuses on the prediction of heat flux with the help of measured transient temperature data. Thin film gauges are one of the most predominant method for the heat flux prediction especially for short duration transient temperature measurement. Thin film gauges are usually exposed to the heated environment for the measurement purpose. However, there are some prominent research areas like ablation phenomenon met to spacecraft thermal shields during re-entry to the atmosphere, for which direct exposure of the thin film gauge to the heated environment causes the functional and working difficulties associated with the gauge. In the present study, it is aimed to investigate the suitability of thin film gauge for the conduction-based short duration measurement. An experimental set up is fabricated, which is used to supply the heat load to the hand-made thin film gauge using platinum as sensing element and quartz as a substrate. The transient temperature data is recorded during experiment is further compared with the simulated temperature histories obtained through finite element analysis. The heat flux estimation for both the analysis is made using measured transient temperature data by convolute integral of one- dimensional heat conduction equation. The estimated heat flux value for the experimental and numerical result is found to be in excellent agreement.
