Viskanta, West Lafayette, Indiana Aims and Scope: Numerical Heat Transfer, Part A: Applications is an international vehicle for the publication of numerically based, results-oriented papers dealing with problems in heat transfer, mass transfer and fluid flow. The underlying numerical solutions may be based either on available methodology or on adaptations or moderate extensions of available methods. The presentation of experimental results which support the numerical solutions is also acceptable. However, papers whose main focus is on innovative numerical methodology development should be submitted to a companion journal, Numerical Heat Transfer, Part B: Fundamentals. This journal will be published in two volumes, each containing four issues, for a total of eight issues scheduled for publication in 1991. Abstracted and/or Indexed in: Current Contents, Information Service in Mechanical Engineering (ISMEC), Science Citation Index, Nova Information Services Co., and Engineering Information, Inc.
