![]() The algorithms and interfaces for each module are uniquely tailored for the particular application – thus avoiding the frequently-steep learning curves associated with much more powerful, commercially available and often costly CFD packages. About thirty (30) “mini-modules,” which use a combination of an Excel spreadsheet for input and graphical display of output and Visual Basic for Applications (VBA) macros for the serious calculations, have also been developed and may be downloaded here. We have developed software modules for ten (10) fundamental topics in heat transfer. By combining this more fundamental approach with enhanced color-visualization techniques, these software modules allow a student to “see” - and thus perhaps to understand - the physics underlying a particular process. ![]() Often the result was a facility for doing more conventional calculations, only faster and usually the computed result was just a single “answer” - such as an overall convective heat-transfer coefficient or fin efficiency.īy contrast, our software uses modern numerical algorithms to solve the fundamental governing ordinary or partial-differential equations in real time. They didn’t teach you in school about heat transfer”.In the past most instructional-software packages for heat & mass transfer were based on the “computerization” of existing analytical solutions and experimental correlations. Tackle that problem, have a read of our White Paper “What To learn more about heat transfer and how Simcenter FLOEFD can help you It should either be heated as efficiently as possible (such as our homes) or cooled, and often as quickly or equally as possible as well. In some cases, heat is wanted and in others it is not and the task of us engineers is to optimize its use or dissipation. Everywhere, where there is movement, some form of propulsion or electricity, there is heat generated through friction, chemical reaction or electric losses. Thermal management is key in so many engineering disciplines – from brake cooling in cars, to gearbox or bearing cooling in wind power plants, cooling of electronics in smartwatches, mobile phones, as well as computers on our desks, on planes, trains and other means of transportation. Heat exchanger performance simulation and design comparison. ![]() I can also clearly hear the fan humming as it cools s the processor. In this case, the heat is dissipating by natural convection on the display and by radiating off of its large surface area or conducting onto the table it stands on together with the rest of the heat generated by the laptop and even into the palm of my hands resting on the keyboard. All of them conduct the generated heat into the laptop structure, as well as any other components and objects in contact with them. While I’m writing this blog post, my laptop is generating heat at various places: the processors and chips, the battery that is getting drained and the LED screen. When it’s cold outside we use heaters which work by conduction, convection and radiation – the three key heat transfer mechanisms. Now coming back to the engineering topic of cooling, this effect in spray or film cooling, as well as other heat transfer mechanisms, is applied in almost everything. Preventing our bodies from sweating under such conditions can cause us to overheat. This process helps our body to stay cool, no matter if it’s due to a high fever when we are sick or run a marathon. The evaporation of our sweat consumes energy (latent heat) which our body wants to get rid of in form of heat. In most cases, sweating is not required but when our body works out more and we start to sweat, the body applies the laws of physics very naturally. The human body regulates its heat through the largest organ of our body – our skin. We sweat when we play sports, run for the subway or train or lay on the beach. One essential heat transfer that everyone is familiar with, although maybe not understand its use, is sweating. Heat transfer is an essential part of our daily lives and often not even recognized as we go about with our lives. Transient animation of the natural convection over a heated flat plate.
