67) The time constant represents the relative amount of thermal storage capacity. The convective heat transfer number measures the relative strength of convective heat transfer at the thermal mass surface. A large value of the convective heat transfer number means that the convective heat transfer is very effective compared with the flow mixing in the room. In this case, the thermal mass can be considered to be in equilibrium with the room air temperature. The role of the convective heat transfer number is analogous to the Biot number in heat transfer.
For example, = ¯ + , where an over bar denotes averaging. In theory, we consider the ensemble average that takes the average over many identical experiments. In practice, the average is usually a time average. 14 Examples of free shear flows: (a) a jet flow; (b) a mixing layer flow; (c) a wake flow. One can also present these definitions by the concept of probability distribution function P u . P u is defined for a velocity component u at one point, so that the probability that the fluctuation velocity is between u and u + du is P(u)du.
E. from the potential energy to the turbulence. e. from the turbulence kinetic energy to thermal internal energy. This is the basic concept of all the turbulence energy equation models. If the length scale l is related to some flow dimensions, we have the so-called one-equation models. One such model is for thin shear flows in which case the Airflow, heat and mass transfer in enclosures 37 length scale l is taken as proportional to the mixing length. 124) where CD is a model constant. Advantages of the one-equation model over a mixing length model are very limited.
