. In the forced convection the fluid to be heated is blown or pumped past the heated surface by employing a pump or a fan while in the natural or free convection fluid flow is naturally achieved based. The physical properties µ k ρ c p of a fluid are temperature dependentUndoubtedly the accuracy of the results obtained by using theoretical relations and the dimensionless empirical correlations would depend upon the temperature. Forced Convection Full technical laboratoryresearch report This is my last full tech and last lab report overall.
This results in a larger total heat transfer for the forced convection than the free convection. The results from pin fins made of copper aluminum and stainless steel showed. Forced convection It is assumed that the velocity of the fluid is zero at the wall this assumption is called no-slip condition.

In this article we will discuss about the empirical correlations for free and forced convection. Bulk Temperature and Mean Film Temperature. To make fundamental measurements of both free and forced convection heat transfer along with measurements of flow velocity and turbulence intensity.
Thermocouples measure the air temperature upstream and downstream of the surface and the temperature at the heat transfer surface. I am glad it has all finally come to an end after spending numerous late nights getting these reports. Convection is classified as Natural or free and Forced convection depending on how the fluid motion is initiated.
Furthermore in free convection the fluid motion is caused by means such as gravity buoyancy rise and fall of warmer can cooler fluid respectively etc and in forced convection the flow of fluid is forced over a surface or in a tube through internalexternal means fans pumps etc. Armfield HT19 Free and Forced Convection Heat Transfer 12 Procedure 121 Natural convection To make natural convection firstly the plate was heated up by the resistance with 8 12 15 and 20 volts respectively.

Forced Convection Heat Transfer 81 Introduction The general definition for convection may be summarized to this definition energy transfer between the surface and fluid due to temperature difference and this energy transfer by either forced external internal flow or natural convection. Abstract The purposes of this experiment are to determine pin fin effectiveness and convective heat transfer coefficients for free and forced convection over pin fins of differing length and material. Top 11 Aug 2013 Free and Forced Convection Lab Report Free download as.
