En este trabajo se estudia un problema 2D de transferencia de calor transitoria de un cuerpo bicapa embebido en un fluido en movimiento. Se considera un proceso de transferencia completo teniendo en cuenta la difusión, la disipación convectiva, las pérdidas de flujo lateral, la generación interna de calor y la resistencia térmica que ofrece la interfaz, en la cual se cumple la continuidad del flujo y se presenta un salto de temperatura. La situación de interés se modela matemáticamente, se encuentran soluciones analíticas explícitas utilizando técnicas de Fourier y se formula un esquema convergente en diferencias finitas para simular casos particulares. La solución es consistente con resultados anteriores. Se incluye un ejemplo numérico que muestra coherencia entre los resultados obtenidos y la física del problema.
