Interest lies in obtaining a unique solution tha t satisfies the equations and bound-ary conditions. This may be termed as the direct or forward solution. However\, there are many problems\, partic ularly in practi-cal systems\, where the desired result is known\, but the conditions needed for achieving this are unknown. These are generally kno wn as inverse problems and are of particular interest in thermal processes and systems. For instance\, the temperature\, shear\, or pressure variati on to which a component must be subjected to obtain desired characteristic s in a manufacturing sys-tem is known or prescribed. However\, the boundar y and initial conditions\, in terms of heat input\, pressure\, flow rate a nd tem-perature\, are not known and must be determined by solving the inve rse problem. Such problems are commonly encountered in practical thermal p rocesses.\n\nThis lecture focuses on inverse problems in thermal convectio n and considers a few fundamental and practical circumstances. The inverse convection problems of a thermal plume or jet in cross flow and of a heat source on a vertical flat plate are of par-ticular interest in environmen tal problems and in fire safety. The inverse problem involves determinatio n of the strength and location of the heat source or the jet by employing a few selected data points downstream. A major concern is the non-uniquene ss of the solution and optimization techniques are used to reduce the unce rtainty. A predictor-corrector strategy is outlined\, along with optimizat ion to minimize the data points needed and to ensure uniqueness of the sol ution. Another ap-proach based on search and optimization is developed to solve the inverse natural convection flow due to a finite heat source\, su ch as an electronic component or a fire\, on a wall. Similarly\, another p roblem considered here is a furnace whose wall tem-perature distribution i s not known\, but a few selected data points on a rod at the center of the furnace are used to solve the inverse problem to determine the wall tempe rature to a fair level of accuracy and uniqueness. Again\, optimization of the pro-cess is used to develop an efficient approach and obtain an essen tially unique solution. These basic approaches can be extended to other in verse convection transport problems and a few additional examples are give n.\n\n \n\nBiography\n\nDr. Jaluria is Board of Governors Professor and Di stinguished Professor at Rutgers\, the State University of New Jersey.
