A computational experiment was conducted in the software product Ansys Fluent. Bodies of complex shape can always be represented as a combination of simpler ones, for which it is easy to explore and calculate the flow paths, on the basis of which analytical methods for calculating aerodynamic characteristics are compiled. Heat sink is an aerodynamic process, a process of heat mass transfer of a substance, and aerodynamic characteristics and, in particular, the nature of streamlining of bodies of the simplest forms are of great scientific and practical interest. To ensure the normal operation of the system, it is necessary to cool the parts contacting the hot gases, removing heat from them to the atmosphere directly, or using an intermediate body (water, low-freezing liquid). Maintaining the optimum thermal state of machine parts within the specified limits is necessary to prevent heating, which can cause violations of normal operating conditions, and, as a result, increased wear, jamming and breakage of parts. The relevance of cooling or heat sink systems for mechanical engineering is not in doubt. As one of the nation’s premier heat transfer products firms noted in their seminars on Tier IV requirements, “Outside of the core, the fan is the most important component of the cooling package.The paper presents the results of the study of possibility using a body with an optimized shape with a minimum aerodynamic drag force as a heat sink in a convective gas flow for cooling machine parts. In fact, select airfoil fans have the narrow axial depth necessary to provide the required cooling performance in the tight engine compartments that result from Tier IV. The 4Z, 5Z and 6W blades each can be tailored as an engine cooling fan, a condenser fan, a radiator fan or an oil cooler fan. The high efficiency blade design has also made Multi-Wing’s airfoil profiles a great answer for the challenges of the Tier IV emissions standards. The airfoil’s low power consumption saves power while reducing noise, making it a high efficiency solution for a spectrum of cooling applications. Airfoil fans may be configured as either blowers or suckers, and the blades may also have varying pitch angles to control air volume. Multi-Wing’s airfoil design has a broad operating range, making it suitable for everything from the most demanding engine-cooling applications to essentially any ventilation requirement. Cooling tower fans, radiator fans, HVAC fans, refrigeration fans.Airfoil blade provides low power consumption.Twisting the blade reduces vortex shedding along the profile.Most efficient design in optimized conditions.In axial fans, the airfoil’s twisted design ensures that the incident angle between the airfoil and the airflow is constant along the blade length, giving a uniform blade loading for high efficiency, low noise fans.

#Define airfoil series

Airfoil impellers function just like a series of small airplane wings attached to a hub, with one notable exception. This creates lift in an airplane wing or airflow in an impeller. Air is deflected across the convex curve along the top of the blade and along the flat or concave curve on the bottom of the blade, and flows downward over the sharp trailing edge as it leaves the blade.Īccording to Bernoulli’s Principle, the faster moving air across the top of the blade creates less pressure than the slower moving air on the bottom of the blade. As air approaches the blade’s leading edge, the stream splits and travels above and below the blade. Airfoil impellers have a round leading edge, a sharp trailing edge, and in profile or cross section, look similar to a teardrop that has been flattened on one side. Multi-Wing America’s airfoil impellers provide uniform, high volume airflow with low power consumption for optimum efficiency using the same aerodynamics that create flight. Airfoil fan blades provide efficiency and low noise using classic airfoil design
