Paper presented at the 6th International Conference on Heat Transfer, Fluid Mechanics and Thermodynamics, South Africa, 30 June - 2 July, 2008.; An experimental measurements of unsteady wakes behind a
sinusoidally plunging airfoil was surveyed with a Hot-wire
rake containing seven I-wires. The aim of these
measurements was to study the velocity profiles behind the
oscillating airfoil trailing edge. Influences of reduced
frequency and angle of attack were studied in details. It was
shown that the angle of attack and reduced frequency are
the most important parameters which influence on the
velocity profiles. The momentum deficit was relative to
reduced frequency and amplitude of oscillation and its
behaviours were changed after static stall angles. At the
angle of attack beyond static stall angle flow separation
causes increasing the momentum deficit. The velocity
profile has approximately symmetric shape profile.
Data were taken at mean incidence angles of 0, 8 degrees at
reduced frequencies of 0.09 to 0.56. The nondimensional
amplitude of oscillation was 0.27. The corresponding
Reynolds numbers, based on the chord length, were 25000
and 150000.

Paper presented at the 6th International Conference on Heat Transfer, Fluid Mechanics and Thermodynamics, South Africa, 30 June - 2 July, 2008.; The concept of heat integration in batch chemical plants has been in literature for more than a decade. Heat
integration in batch plants can be effceted in 2 ways, i.e. direct and indirect heat integration. Direct heat
integration is encountered when both the source and the sink processes have to be active over a common time
interval, assuming that the thermal driving forces allow. On the other hand, indirect heat integration allows heat
integration of processes regardless of the time interval, as long as the source process takes place before the sink
process so as to store energy or heat for later use. The thermal driving forces, nonetheless, must still be obeyed
even in this type of heat integration. It is, therefore, evident from the foregoing statements that direct heat
integration is more constrained than indirect heat integration. Presented in this paper is a mathematically
rigorous technique for optimization of energy use through the exploitation of heat storage in heat integrated
multipurpose batch plants. Storage of heat is effected through the use of a heat transfer fluid. The resultant
mathematical formulation exhibits a mixed integer linear programming (MILP) stucture, which yields a globally
optimal solution for a predefined storage size.
